efi: ARM: avoid warning about phys_addr_t cast
memblock_remove() takes a phys_addr_t, which may be narrower than 64 bits,
causing a harmless warning:
drivers/firmware/efi/arm-init.c: In function 'reserve_regions':
include/linux/kernel.h:29:20: error: large integer implicitly truncated to unsigned type [-Werror=overflow]
#define ULLONG_MAX (~0ULL)
^
drivers/firmware/efi/arm-init.c:152:21: note: in expansion of macro 'ULLONG_MAX'
memblock_remove(0, ULLONG_MAX);
This adds an explicit typecast to avoid the warning
Fixes: 500899c2cc3e ("efi: ARM/arm64: ignore DT memory nodes instead of removing them")
