[PATCH v3 1/9] arm64/debug: Eliminate magic number for size of BRK instruction

[Dave Martin]

The size of an A64 BRK instruction is the same as the size of all other
A64 instructions, because all A64 instructions are the same size.

BREAK_INSTR_SIZE is retained for readibility, but it should not be
an independent constant from AARCH64_INSN_SIZE.
