If NPU power is guaranteed always on parts of driver setup can be omitted to reduce the number of cycles required to setup the NPU drivers.
By enabling dev_power_always_on, the setup cycles are reduced by approx. ~50%. (4462->2238 in prologue, 1167->642 in epilogue)

The addition of init_v3 accidentely changed default values for soft
resetting Ethos-U. Restore the default parameters to non-secure, user
mode for init_v1 and init_v2 and also make sure to check return value
from ethosu_soft_reset.

The ETHOSU is soft-reset only if the previous job failed or if
the current privilege level is not user or if the current security
level is not secure.

This includes resetting the Ethos-U and restoring the
previosuly saved PMU configuration (if any).

This change is done as a prerequisite to be able to set
base address for NPU through ethosu_init(). So instead of using
a mamory mapped struct we use the same functions to read/write
PMU registers as the rest of the ethos-u driver.

Turn the IRQ initialization around, to have the application define the
interrupt handler and expose the driver routine that is to be called
when that happens.
