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.

To make the framework suit all Andes CPUs, change all occurrences of
andes45 to andes.
In addition, we fix some coding style problems and remove an unused
macro in andes.h.

Before the ratification of Sscofpmf, the Andes PMU extension
was designed to support the sampling and filtering with hardware
performance counters (zihpm), it works with the current SBI PMU
extension and Linux SBI PMU driver.
We implement 1) the PMU device callbacks that update the
corresponding bits on custom CSRs, 2) extentions_init() to detect
the hardware support of Andes PMU and initialize the per-hart
PMU related CSR, and 3) pmu_init() to register PMU device and
populate event mappings.
Also define a andes_pmu_setup() function which is in preparation
for adding default PMU mappings in andes_hpm.h
