Subject: [PATCH v4 0/5] add support for T7 family clock controller

It introduces three clock controllers:
- SCMI clock controller: these clocks are managed by the SCP and handled through SCMI.
- PLL clock controller.
- peripheral clock controller.

Changes v4 since v4 at [2]:
- drop amlogic_t7_pll_probe, use meson_clkc_mmio_probe instead
- add CLK_DIVIDER_MAX_AT_ZERO for pcie_pll_od clk
- add frac for hifi_dco_pll_dco
- add l_detect for mclk_pll_dco
- drop v3 5/6 patch, and use MESON_PCLK
- drop SPI_PWM_CLK_XX macro and use MESON_COMP_XX
- drop the register's prefix

Changes v3 since v2 at [2]:
- update T7 PLL YAML
- add 't7_' prefix for t7 clock name and variable in t7-pll.c and t7-peripherals.c
- correct v1 patch link
- add new macro MESON_PCLK_V2
- update the driver,header,yaml file license

Changes v2 since v1 at [1]:
- add CLK_MESON import
- add const for clkc_regmap_config in PLL driver
- fix eth_rmii_sel parent
- update T7 PLL YAML file
