This patchset introduces a "Secure Power Doamin Controller". In A1/C1, power
controller registers such as PWRCTRL_FOCRSTN, PWRCTRL_PWR_OFF, PWRCTRL_MEM_PD
and PWRCTRL_ISO_EN, are in the secure domain, and should be accessed from ATF
by smc.

Changes since v3 at [2]:                                                         
 - remove phandle to secure-monitor node

Changes since v2 at [1]:
- update domain id
- include dt-bindings in dts

Changes since v1 at [0]:
- use APIs from sm driver
- rename pwrc_secure_get_power as Kevin suggested
- add comments for always on domains
- replace arch_initcall_sync with builtin_platform_driver
- fix coding style
