clk: spacemit: re-enable PLLs after init
0af1b7b 
The PLL and PLLA init callbacks gate off and reprogram a PLL when its
firmware configuration is absent from the rate table. However, they
leave the PLL gated off after updating the registers.

Re-enable the PLL to complete the sequence and propagate any lock
timeout to clock registration.

Fixes: 3a08623 ("clk: spacemit: ccu_pll: add plla type clock")

clk: spacemit: k3: add 1.8 GHz PLL5 and PLL8 rates
d3f5464 
The K3 SoC may not remain stable when its A100 CPU clusters operate
persistently at 2 GHz. Updated U-Boot firmware therefore configures
their C2 and C3 clock domains at 1.8 GHz during early initialization.
PLL5 feeds C2 and PLL8 feeds C3, but 2 GHz is currently the only entry
in both rate tables.

Add 1.8 GHz as the first entry in the PLL5 and PLL8 rate tables,
switching the driver default from 2 GHz to 1.8 GHz.
