KVM: arm64: selftests: Remove a duplicate register listing in set_id_regs

Browse source

Currently we list the main set of registers with bits we test three
times, once in the test_regs array which is used at runtime, once in the
guest code and once in a list of ARRAY_SIZE() operations we use to tell
kselftest how many tests we plan to execute. This is needlessly fiddly,
when adding new registers as the test_cnt calculation is formatted with
two registers per line. Instead count the number of bitfields in the
register arrays at runtime.

The existing code subtracts ARRAY_SIZE(test_regs) from the number of
tests to account for the terminating FTR_REG_END entries in the per
register arrays, the new code accounts for this when enumerating.
