media: platform: rzg2l-cru: Use v4l2_fill_pixfmt()

Browse Source 
Rather than open-code a calculation of the format's bytesperline
and sizeimage, use the v4l2_fill_pixfmt() helper. This makes it
easier to support the CRU packed pixel formats without over
complicating the driver.

This change makes the .bpp member of struct rzg2l_cru_ip_format
superfluous - remove them.
