[PATCH RESEND v7 0/4] clk: meson: add a sub EMMC clock controller support

[Jianxin Pan]

This driver will add a MMC clock controller driver support.
The original idea about adding a clock controller is during the
discussion in the NAND driver mainline effort[1].

This driver is tested in the S400 board (AXG platform) with NAND driver.

Changes since v6 [7]:
 - add one based support for sclk divier
 - alloc sclk in probe for multiple instance
 - fix coding styles

Changes since v5 [6]:
 - remove divider ops with .init and use sclk_div instead
 - drop CLK_DIVIDER_ROUND_CLOSEST in mux and div
 - drop the useless type cast 

Changes since v4 [5]:
 - use struct parm in phase delay driver
 - remove 0 delay releted part in phase delay driver
 - don't rebuild the parent name once again
 - add divider ops with .init

Changes since v3 [4]:
 - separate clk-phase-delay driver
 - replace clk_get_rate() with clk_hw_get_rate()
 - collect Rob's R-Y
 - drop 'meson-' prefix from compatible string

 Changes since v2 [3]:
 - squash dt-binding clock-id patch
 - update license
 - fix alignment
 - construct a clk register helper() function

Changes since v1 [2]:
 - implement phase clock
 - update compatible name
 - adjust file name
 - divider probe() into small functions, and re-use them
