soc: infineon: psoc4100smax: Setup IMO for 48MHz

Correct a clock initialization ordering issue where IMO, an internal
high speed oscillator, was being setup before ILO. This does not match
the MTB initialization order and would cause the part to fault.

Sets up the default clock configuration on the part to be 48MHz. Adjusts
the default WCO (low speed external crystal source) to be 32768 as the
eval board has this crystal on it. Enables common clock elements
(hf_clk, clock_pump) as needed in the part dts rather than the board.
