drm/tinydrm/mipi-dbi: Add mipi_dbi_init_with_formats()
The MIPI DBI standard support more pixel formats than what this helper
supports. Add an init function that lets the driver use different
format(s). This avoids open coding mipi_dbi_init() in st7586.
st7586 sets preferred_depth but this is not necessary since it only
supports one format.
v2: Forgot to remove the mipi->rotation assignment in st7586,
mipi_dbi_init_with_formats() handles it.
