pmdomain: amlogic: Constify struct meson_secure_pwrc_domain_desc
'struct meson_secure_pwrc_domain_desc' is not modified in this driver.
Constifying this structure moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig, as an example:
Before:

Add the missing invocation of the MODULE_DESCRIPTION() macro to all

This includes meson-secure-pwrc.c which, although it did not produce a
warning with the x86 allmodconfig configuration, may cause this
warning with other configurations where CONFIG_MESON_SM is enabled.

pmdomain: amlogic: Fix mask for the second NNA mem PD domain
Without this change, the NPU hangs when the 8th NN core is used.
It matches what the out-of-tree driver does.
