SoC attributes update for v5.9

1. Addition of ARM SMCCC ARCH_SOC_ID support
2. Usage of the custom soc attribute groups already supported in the
   infrastucture instead of device_create_file which eliminates the need
   for any cleanup when soc is unregistered
3. Minor clean up switching to use standard DEVICE_ATTR_RO() instead of
   direct __ATTR
