Move all the format configuration to the subdevice state and simplify the format handling, locking and initialization. While at it, simplify imx214_start_streaming() by removing unneeded goto statements and the corresponding error label.

(The 8 is 4 lanes and DDR.) Parsing the PLL registers with the defined 24MHz input. We're in single PLL mode, so MIPI frequency is directly linked to pixel rate. VTCK ends up being 1200MHz, and VTPXCK and OPPXCK both are 120MHz. Section 5.3 "Frame rate calculation formula" says "Pixel rate [pixels/s] = VTPXCK [MHz] * 4", so 120 * 4 = 480MPix/s, which basically agrees with my number above. 3.1.4. MIPI global timing setting says "Output bitrate = OPPXCK * reg 0x113[7:0]", so 120MHz * 10, or 1200Mbit/s. That would be a link frequency of 600MHz due to DDR. That also matches to 480MPix/s * 10bpp / 4 lanes / 2 for DDR. Keep the previous link frequency for backward compatibility.
