firmware: arm_scmi: Simplify enable/disable clock operations
SCMI clock enable/disable operations come in 2 different flavours which
simply just differ in how the underlying SCMI transactions is carried on:
atomic or not.
Currently we expose such SCMI operations through 2 distinctly named
wrappers, that, in turn, are wrapped into another couple of similarly and
distinctly named callbacks inside SCMI clock driver user.
Reduce the churn of duplicated wrappers by adding a param to SCMI clock
enable/disable operations to ask for atomic operation while removing the
_atomic version of such operations.
No functional change.
