rS338022: Fix casts between 64-bit physical addresses and pointers in EFI.
Summary

Compiling FreeBSD/i386 with modern GCC triggers warnings for various
places that convert 64-bit EFI_ADDRs to pointers and vice versa.

  • Cast pointers to uintptr_t rather than to uint64_t when assigning to a 64-bit integer.
  • Cast 64-bit integers to uintptr_t before a cast to a pointer.
Test Plan
  • build world with CROSS_TOOLCHAIN=i386-gcc
