Changes for FPV sensor modes

Higher FPS imx335 sensor driver on Goke/Hisilicon SoCs.

Sensor modes added:

2592x1520 50fps , slightly cropped vertically to 16:9

for on hi356ev300 : Isp_FrameRate=50 , majestic set to 1920x1080 50fps => 50fps
for gk7205v300 : Isp_FrameRate=48 , majestic set to 1920x1080 48fps => 47fps

2592x1944 fullscale mode boosted to 40fps

for on hi356ev300 set Isp_FrameRate=45, majestic to 1920x1080 fps: 45 to get 39fps for on gk7205v300 set Isp_FrameRate=36, majestic to 1920x1080 fps: 36 to get 33fps

1920x1080 cropped, max 90fps , zoom 1.5x

Isp_FrameRate=90 # can work at 90fps only when majestic is set to 1280x720 !!!
Max Isp_FrameRate=55 for 1920x1080

1296x972 binning max 65fps,

Isp_FrameRate=68 # # max supported value on hi356ev300 at 1280x720

2592x1944 stock fullscale 30fps mode

set Isp_FrameRate=30 to enable this mode
