dt-bindings: soc: spacemit: k3: add clock support

Browse source

Add compatible strings for clock drivers to support Spacemit K3 SoC,
also includes all the defined clock IDs.

The SpacemiT K3 SoC clock IP is scattered over several different blocks,
which are APBC, APBS, APMU, DCIU, MPMU, all of them are capable of
generating clock and reset signals. APMU and MPMU have additional Power
Domain management functionality.

Following is a brief list that shows devices managed in each block:

APBC: UART, GPIO, PWM, SPI, TIMER, I2S, IR, DR, TSEN, IPC, CAN
APBS: various PPL clocks control
APMU: CCI, CPU, CSI, ISP, LCD, USB, QSPI, DMA, VPU, GPU, DSI, PCIe, EMAC..
DCID: SRAM, DMA, TCM
MPMU: various PLL1 derived clocks, UART, WATCHDOG, I2S
