pmdomain: thead: Fix error pointer vs NULL bug in th1520_pd_reboot_init()
The devm_auxiliary_device_create() returns NULL on error. It never
returns error pointers. Using PTR_ERR_OR_ZERO() here means the function
always returns success. Replace the PTR_ERR_OR_ZERO() call check with
a NULL check.

pmdomain: thead: fix TH1520_AON_PROTOCOL dependency
Kconfig treats the dependency as optional, but the header file only provides
normal declarations and no empty API stubs:

Since the firmware code can easily be enabled for compile testing, there
is no need to add stubs either, so just make it a hard dependency.
