Update mtk common clock driver to support mt8512
1. add new set_clr_upd mux type and related operation
2. add configurable pcw_chg_reg/ibits/fmin to mtk_pll
3. fix mtk_clk_find_parent_rate data overflow

To: u-boot
This patch adds mmc support for MediaTek MT8512/MT8110 SoCs.
MT8512/MT8110 SoCs puts the tune register at top layer, so
need add new code to support it.

For CMD21 tuning data, the 128/64 bytes data may coming in very
short time, before msdc_start_data(), the read data has already
come, in this case, clear MSDC_INT will cause the interrupt disappear
and lead to the thread hang.
the solution is just clear all interrupts before command was sent.

This adds a general board file based on MT8512 SoCs from MediaTek.
Apart from the generic parts (cpu) we add some low level init codes
and initialize the early clocks.
This commit is adding the basic boot support for the MT8512 eMMC board.
