We update generic platform to use kconfig for enabling/disabling
platform overrides. We also enable all platform overrides in generic
platform defconfig.

platform: Add HSM implementation for Allwinner D12022-06-13T06:29:09ZSamuel Hollandsamuel@sholland.org2022-06-13T01:03:55Zurn:sha1:9dc5ec5c519b2ec1702e13a97b9e595ee5d94bf6
Allwinner D1 contains a "PPU" power domain controller which can
automatically power down/up the CPU power domain. This power domain
includes the C906 core along with its CLINT and PLIC.
This HSM implementation supports non-retentive hart suspend by:
1) Saving/restoring state that is lost during hart suspend,
2) Performing cache maintenance before/after hart suspend,
3) Configuring wakeup sources before hart suspend, and
4) Asking the PPU to power down the hart when it enters WFI.
Since this HSM implementation is for a single-core SoC, it does not need
to worry about concurrency or saving multiple instances of state.
