Subject[PATCH] mfd: sun6i-prcm: fix build warning for non-OF configurations
When CONFIG_OF is disabled, we get a harmless warning about an
unused variable:

drivers/mfd/sun6i-prcm.c: In function 'sun6i_prcm_probe':
drivers/mfd/sun6i-prcm.c:151:22: error: unused variable 'np' [-Werror=unused-variable]

Remove the variable and open-code the value in the only place
it is used, so it can get left out as well without CONFIG_OF.

Fixes: a05a2e7998ab ("mfd: sun6i-prcm: Allow to compile with COMPILE_TEST")
