ARM: 7822/1: add workaround for ambiguous C99 stdint.h types

The C99 types uintXX_t that are usually defined in 'stdint.h' are not as
unambiguous on ARM as you would expect. For the types below, there is a
difference on ARM between GCC built for bare metal ARM, GCC built for glibc
and the kernel itself, which results in build errors if you try to build with
-ffreestanding and include 'stdint.h' (such as when you include 'arm_neon.h'
in order to use NEON intrinsics)

As the typedefs for these types in 'stdint.h' are based on builtin defines
supplied by GCC, we can tweak these to align with the kernel's idea of those
types, so 'linux/types.h' and 'stdint.h' can be safely included from the same
source file (provided that -ffreestanding is used).

                   int32_t         uint32_t               uintptr_t
bare metal GCC     long            unsigned long          unsigned int
glibc GCC          int             unsigned int           unsigned int
kernel             int             unsigned int           unsigned long
