isl: drop min row pitch alignment when set by the driver
When the caller of the isl_surf_init() specifies a row pitch, do not
consider the minimum CCS requirement if it's incompatible with the
caller's value.
isl_surf_get_ccs_surf() will check that the main surface alignment
matches CCS expectations.
v2: Simplify checks (Nanley)
v3: Add Comment about isl_surf_get_ccs_surf() (Jason)
