[PATCH 2/3] arm64: efi-entry.S: avoid open-coded adr_l

[mark.rutland@arm.com (Mark Rutland)]

Some places in the kernel open-code sequences using ADRP for a symbol
another instruction using a :lo12: relocation for that same symbol.
These sequences are easy to get wrong, and more painful to read than is
necessary. For these reasons, it is preferable to use the
{adr,ldr,str}_l macros for these cases.

This patch makes use of these in efi-entry.S, removing open-coded
sequences using adrp.
