The variable result is being initialized with a value that is never
read, it is being updated immediately afterwards in both branches
of an if statement. The assignment is redundant and can be removed.

A recent change added a new BOOTUP_DEFAULT power profile mode
to the PP_SMC_POWER_PROFILE enum but omitted updating the
corresponding profile_name array. Fix this by adding in the
missing BOOTUP_DEFAULT to profile_name[].

In the case where is_enable is false and lo_base_addr is non-zero the
variable ret has not been initialized and is being checked for non-zero
and potentially garbage is being returned. Fix this by not returning
ret but instead returning -EINVAL on the zero lo_base_addr case.
From: Colin Ian King
The variable actual_clock is being initialized however this is never
read and later it is being reassigned to a new value. The initialization
is redundant and hence can be removed.

Currently when the allocation of ppgtt->work fails the error return
path via err_free returns an uninitialized value in err. Fix this
by setting err to the appropriate error return of -ENOMEM.
