platform: generic: Modify platform ops instead of using hooks

Browse Source 
Switch all existing platform overrides to use the helper pattern instead
of the platform hooks. After this commit, only the .match_table and
.init members of struct platform_override are used.

There are two minor behavioral differences:
 - For Allwinner D1, fdt_add_cpu_idle_states() is now called before the
   body of generic_final_init(). This should have no functional impact.
 - For StarFive JH7110, if the /chosen/starfive,boot-hart-id property is
   missing, the code now falls back to using generic_coldboot_harts,
   instead of accepting any hart.
