The gpio controller in rockchips SoC in a child of the pinctrl driver
and cannot control pullups and pulldowns.
Use the new fdt_pinctrl interface for accessing pin capabilities and
setting them.
We can now report that every pins is capable of being IN or OUT function
If the pin isn't in gpio mode no changes will be allowed.

Most of the gpio controller cannot configure or get the configuration
of the pin muxing as it's usually handled in the pinctrl driver.
But they can know what is the pinmuxing driver either because they are
child of it or via the gpio-range property.
Add some new methods to fdt_pinctrl that a pin controller can implement.
Some methods are :
fdt_pinctrl_is_gpio: Use to know if the pin in the gpio mode
fdt_pinctrl_set_flags: Set the flags of the pin (pullup/pulldown etc ...)
fdt_pinctrl_get_flags: Get the flags of the pin (pullup/pulldown etc ...)

The defaults method returns EOPNOTSUPP.

Some consumer cannot know the voltage of the regulator without it.
While here, refuse to attach is min_voltage != max_voltage, it

Each GPIO bank is powered by a different pin and so can be powered at different
voltage from different regulators.
Add a new config that now hold the pinmux data and the banks available on each
Since the aw_gpio driver being also the pinmux one it's attached before the PMIC
so add a config_intrhook_oneshot function that will enable the needed regulators
when the system is fully functional.

Profiling library archives are part of the development environment; they
don't need to be in separate -profile packages.

(In fact we can probably just eliminate the _p.a archives assuming that
profiling will be done using hwpmc etc., but that is a change for later.)

`cat -l` is needed during the installworld phase and other system's cat
don't support that flag. To avoid portability issues when compiling on
Linux/macOS (such as the the direct access to &fp->_mbstate), we
disable the entire multibyte support when building as a boostrap tool.

[MIPS][ELF] Use PC-relative relocations in .eh_frame when possible

  When compiling position-independent executables, we now use
  DW_EH_PE_pcrel | DW_EH_PE_sdata4. However, the MIPS ABI does not define a
  64-bit PC-relative ELF relocation so we cannot use sdata8 for the large
  code model case. When using the large code model, we fall back to the
  previous behaviour of generating absolute relocations.

  With this change clang-generated .o files can be linked by LLD without
  having to pass -Wl,-z,notext (which creates text relocations).
  This is simpler than the approach used by ld.bfd, which rewrites the
  .eh_frame section to convert absolute relocations into relative references.

  I saw in D13104 that apparently ld.bfd did not accept pc-relative relocations
  for MIPS ouput at some point. However, I also checked that recent ld.bfd
  can process the clang-generated .o files so this no longer seems true.

Merge commit 8e8ccf47 from llvm git (by me)

  [MIPS] Don't emit R_(MICRO)MIPS_JALR relocations against data symbols

  The R_(MICRO)MIPS_JALR optimization only works when used against functions.
  Using the relocation against a data symbol (e.g. function pointer) will
  cause some linkers that don't ignore the hint in this case (e.g. LLD prior
  to commit 5bab291) to generate a relative branch to the data symbol
  which crashes at run time. Before this patch, LLVM was erroneously emitting
  these relocations against local-dynamic TLS function pointers and global
  function pointers with internal visibility.

These two changes should allow using lld for MIPS64 (and maybe also MIPS32)
by default.
The second commit is not strictly necessary for clang+lld since LLD9 will
not perform the R_MIPS_JALR optimization (it was only added for 10) but it
is probably required in order to use recent ld.bfd.
