media: platform: rzg2l-cru: rzg2l-csi2: Restructure vclk handling

Browse source

As per section 35.3.1 Starting Reception for the MIPI CSI-2 Input on the
latest hardware manual (R01UH0914EJ0145 Rev.1.45) we need to disable the
vclk before enabling the LINK reception and enable the vclk after enabling
the link Reception. So restructure vclk handling as per the HW manual.
