[PATCH] clk: vf610: Add support for the Ethernet switch clocks

[Lukasz Majewski]

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).
