clk: vf610: Add support for the Ethernet switch clocks
The vf610 device has built in the MoreThanIP L2 switch. For proper
operation it is required to enable ESW and MAC table lookup
clocks.
The MAC table spans from 0x400E_C000 for 0x4000 and it is necessary
to provide clocks for each AIPS1-"slot", which size is 0x1000
(hence four separate entries).
Those can be enabled via clock gating CCM_CCGR10 register
(0x4006_B068).
