As per kernel documentation, use raw_spinlock_t only in real critical core
code, low-level interrupt handling, and places where disabling preemption
or interrupts is required. Here the lock is for concurrent register access
from different drivers, hence spin_lock() is sufficient.

Reduce critical sections on rz_mtu3_start_stop_ch() and
rz_mtu3_is_enabled() by moving offset and bitpos computation
outside the critical section and drop the 'ret' variable on
rz_mtu3_is_enabled() and return 'tstr & BIT(bitpos)' directly.
