Add the CLK_IGNORE_UNUSED flag to the vp-axi clock (CLK_VP_AXI) to avoid
depending on clk_ignore_unused in the cmdline. Without this fix, the
emmc-sdio clock (CLK_EMMC_SDIO) fails to work after vp-axi is disabled.

This fails to build on 32-bit targets because of a missing __udivdi3.
IIRC the right way to fix that is to avoid the division, but I just want
a tree that builds and the only real T-Head platforms are 64-bit right
now.

Add support for the AP sub-system clock controller in the T-Head TH1520.
This include CPU, DPU, GMAC and TEE PLLs.
