Remove -Wpadded warning

-Wpadded warns whenever the C compiler automatically includes any
padding in a structure. Because TF-A has a large number of structures,
this occurs fairly frequently and is incredibly verbose, and as such is
unlikely to ever be fixed.

The utility of this warning is also extremely limited - knowing that a
structure includes padding does not point to the existence of an error,
and is probably quite unlikely to indicate actually buggy behaviour.
Therefore, it's probably best to keep this warning off at all times.

allwinner: h6: power: Switch to using the AXP driver

Chip ID checking and poweroff work just like they did before.
Regulators are now enabled just like on A64/H5.

This changes the signatures of the low-level register read/write
functions to match the interface expected by the common driver.

allwinner: Convert AXP803 regulator setup code into a driver

Previously, the A64/H5 and H6 platforms' PMIC setup code was entirely
independent. However, some H6 boards also need early regulator setup.

Most of the register interface and all of the device tree traversal code
can be reused between the AXP803 and AXP805. The main difference is the
hardware bus interface, so that part is left to the platforms. The
remainder is moved into a driver.

I factored out the bits that were obviously specific to the AXP803;
additional changes for compatibility with other PMICs can be made as
needed.

The only functional change is that rsb_init() now checks the PMIC's chip
ID register against the expected value. This was already being done in
the H6 version of the code.

These are used by the PMIC setup code, which runs during BL31

They can't be needed before BL31, or it wouldn't be possible to boot.
Allwinner platforms don't generally build anything but BL31 anyway, but
this change improves clarity and consistency with allwinner-common.mk.

- Check the return value from sunxi_init_platform_r_twi().
- Print the PMIC banner before doing anything that might fail.
- Remove double prefixes in error messages.
- Consistently omit the trailing period.
- No need to print the unknown SoC's ID, since we already did that
earlier in bl31_platform_setup().
- On the other hand, do print the ID of the unknown PMIC.
- Try to keep the messages concise, as the large string size in these
files was causing the firmware to spill into the next page.
- Downgrade the banner from NOTICE to INFO. It's purely informational,
and people should be using debug builds on untested hardware anyway.

rockchip: Prevent macro expansion in paths

Instead of stringizing the paths to binary files, add them as string
defines on the command line (e.g. -DFOO=\"BAR\" instead of -DFOO=BAR).
This prevents macros from being expanded inside the string value itself.
For example, -DFOO=/path/with-linux-in-it would have been expanded to
"/path/with-1-in-it" because `linux=1` is one of the standard GCC
defines.

Remove -Wmissing-declarations warning from WARNING1 level

A function declaration declares the name of the function and the type of
the parameter it returns. A function prototype is a function declaration
that also specifies the type of the arguments of the function. Essentially,
a function prototype helps the compiler ensure whether the function call
matches the return type and the right number/type of arguments of function.
A function prototype itself serves as a function declaration for new style
functions.
The warning flag -wmissing-prototype is good enough to check for missing
function prototype and is exhaustive compared to -wmissing-declaration,
therefore making the later redundant.

Note that, at this point, these flags are part of WARNING1 which is not
used for TF-A build by default. Several platforms use upstream libraries
(such as zlib etc) which are in old style c code. After the TF-A build
process is restructred using CMake framework, we plan to enable WARNING1,
WARNING2 and WARNING3 incrementally as the new build platform can compile
each BL binary of a particular platform with set of unique compilation
flags.
