add support for Amlogic A1 clock driver, the clock includes 
three parts: peripheral clocks, pll clocks, CPU clocks.
sys pll and CPU clocks will be sent in next patch.

Changes since v5 at [6]:
-fix yaml file
-add rst/current_en/l_detect parm detection
-remove 'meson_eeclkc_data' in a1.c and a1-pll.c

Changes since v4 at [5]:
- change yaml GPL
- drop meson-eeclk.c patch, add probe function in each driver
- add CLK_IS_CRITICAL for sys_clk clock, drop the flag for sys_a and sys_b
- add new parm for pll, add protection for rst parm
- drop flag for a1_fixed_pll
- remove the same comment for fclk_div, add "refer to"
- add critical flag for a1_sys_clk
- remove rtc table
- rename a1_dspa_en_dspa and a1_dspb_en_dspb
- remove useless comment

Changes since v3 at [3]:
-fix reparenting orphan failed, it depends on jerome's patch [4]
-fix changelist in v3 about reparenting orphan
-remove the dts patch 

Changes since v2 at [2]:
-add probe function for A1
-seperate the clock driver into two patch
-change some clock flags and ops
-add support for a1 PLL ops
-add A1 clock node
-fix reparenting orphan clock failed, registering xtal_fixpll
 and xtal_hifipll after the provider registration, it is not
 a best way.

Changes since v1 at [1]:
-place A1 config alphabetically
-add actual reason for RO ops, CLK_IS_CRITICAL, CLK_IGNORE_UNUSED
-separate the driver into two driver: peripheral and pll driver
-delete CLK_IGNORE_UNUSED flag for pwm b/c/d/e/f clock, dsp clock
-delete the change in Kconfig.platforms, address to Kevin alone
-remove the useless comments
-modify the meson pll driver to support A1 PLLs
