ANDROID: locking/lockdep: Enforce PROVE_RAW_LOCK_NESTING only if PREEMPT_RT

Commit 560af5dc ("lockdep: Enable PROVE_RAW_LOCK_NESTING with
PROVE_LOCKING.") and commit d387ceb1 ("Enforce
PROVE_RAW_LOCK_NESTING only if ARCH_SUPPORTS_RT") cause
PROVE_RAW_LOCK_NESTING to be enabled by default in the GKI. This causes
lockdep to splat during Android init because cpufreq_acct_update_power,
part of the cpufreq_times driver, grabs a non-raw spinlock in an
interrupt context.

While the bug reported by lockdep indicates an error when PREEMPT_RT=y,
this is not an issue in the ACK because PREEMPT_RT is disabled in GKI
builds (and is expected to remain disabled for the time being). Since
lockdep stops monitoring after the first issue it encounters, this splat
also prevents it from detecting any other locking errors later on.

This driver has not been upstreamed, so it is only expected to run with
PREEMPT_RT disabled. This is also the case for several other vendor
drivers that trigger this bug.

Allow PROVE_RAW_LOCK_NESTING to be disabled when !PREEMPT_RT.
