In case of error, the function platform_device_register_simple() returns
ERR_PTR() and never returns NULL. The NULL test in the return value
check should be replaced with IS_ERR().

This is required for the panel to work on bcm911360, where CLCDCLK is

Now that drm_[cm]alloc* helpers are simple one line wrappers around
kvmalloc_array and drm_free_large is just kvfree alias we can drop
them and replace by their native forms.

drm_[cm]alloc* has grown their own kvmalloc with vmalloc fallback
implementations. MM has grown kvmalloc* helpers in the meantime. Let's
use those because it a) reduces the code and b) MM has a better idea
how to implement fallbacks (e.g. do not vmalloc before kmalloc is tried
with __GFP_NORETRY).
drm_calloc_large needs to get __GFP_ZERO explicitly but it is the same
thing as kvmalloc_array in principle.

BCM2835's PLLD_DSI1 divider doesn't give us many choices for our pixel

higher pixel clock rate than requested and adjust the mode we program

With the Cygnus port, we needed to add at least "|| ARCH_BCM_CYGNUS"

anticipate having a port for Kona soon, so just present the module on
all of BCM.
