media: platform: rzg2l-cru: rzg2l-video: Fix start reception procedure 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 supply all the clocks and then release the CRU resets. Currently we are releasing the resets and then supplying the clocks. So, fix the start reception procedure.
