arm64: fix build warning for ARM64_MEMSTART_SHIFT
When building with W=1, the following warning occurs.
arch/arm64/include/asm/kernel-pgtable.h:129:41: error: "PUD_SHIFT" is not defined, evaluates to 0 [-Werror=undef]
129 | #define ARM64_MEMSTART_SHIFT PUD_SHIFT
| ^~~~~~~~~
arch/arm64/include/asm/kernel-pgtable.h:142:5: note: in expansion of macro ‘ARM64_MEMSTART_SHIFT’
142 | #if ARM64_MEMSTART_SHIFT < SECTION_SIZE_BITS
| ^~~~~~~~~~~~~~~~~~~~
The generic PUD_SHIFT was defined in include/asm-generic/pgtable-nopud.h,
however the #ifndef __ASSEMBLY__ guard in this header file makes it unavailable
for assembly files. While someone .S file include the <asm/kernel-pgtable.h>,
the build warning would occur. Now move the macro ARM64_MEMSTART_SHIFT and
ARM64_MEMSTART_ALIGN to arch/arm64/mm/init.c where it is used only, to avoid
this issue.
