clk: meson-gxbb: Add EE 32K Clock for CEC
On Amlogic GX SoCs, there is two CEC controllers :
- An Amlogic CEC custom in the AO domain
- The Synopsys HDMI-TX Controller in the EE domain
Each of these controllers needs a 32.768KHz clock, but there is two paths :
- In the EE domain, the "32k_clk" this patchs is adding
- In the AO domain, with a more complex dual divider more precise setup
The AO 32K clock support will be pushed later in the corresponding
gxbb-aoclk driver when the AE CEC driver is ready.
The EE 32k_clk must be pushed earlier since mainline support for CEC in the
Synopsys HDMI-TX controller is nearby.
