drm: v3d: correct reference to config ARCH_BRCMSTB

Commit 57692c94dcbe ("drm/v3d: Introduce a new DRM driver for Broadcom V3D
V3.x+") adds the config DRM_V3D, which depends on "ARCH_BCMSTB".

Although, a bit confusing: all Broadcom architectures in
./arch/arm/mach-bcm/Kconfig have the prefix "ARCH_BCM", except for
ARCH_BRCMSTB, i.e., the config for Broadcom BCM7XXX based boards.

So, correct the reference ARCH_BCMSTB to the intended ARCH_BRCMSTB.

drm/v3d: Use the new shmem helpers to reduce driver boilerplate.

The new shmem helpers from Noralf and Rob abstract out a bunch of our
BO creation and mapping code.

v2: Use the new sgt getter, and flag pages as dirty before freeing.
v3: Remove the mismatched put_pages.

drm/v3d: add CONFIG_MMU dependency

Without CONFIG_MMU, we get a link error:

drivers/gpu/drm/v3d/v3d_bo.o: In function `v3d_gem_fault':
v3d_bo.c:(.text+0x3ca): undefined reference to `vm_insert_mixed'

The other drivers with this problem already depend on CONFIG_MMU,
so let's do the same thing here.

drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+

This driver will be used to support Mesa on the Broadcom 7268 and 7278
platforms.

V3D 3.3 introduces an MMU, which means we no longer need CMA or vc4's
complicated CL/shader validation scheme. This massively changes the
GEM behavior, so I've forked off to a new driver.

v2: Mark SUBMIT_CL as needing DRM_AUTH. coccinelle fixes from kbuild
test robot. Drop personal git link from MAINTAINERS. Don't
double-map dma-buf imported BOs. Add kerneldoc about needing MMU
eviction. Drop prime vmap/unmap stubs. Delay mmap offset setup
to mmap time. Use drm_dev_init instead of _alloc. Use
ktime_get() for wait_bo timeouts. Drop drm_can_sleep() usage,
since we don't modeset. Switch page tables back to WC (debug
change to coherent had slipped in). Switch
drm_gem_object_unreference_unlocked() to
drm_gem_object_put_unlocked(). Simplify overflow mem handling by
not sharing overflow mem between jobs.
v3: no changes
v4: align submit_cl to 64 bits (review by airlied), check zero flags in
other ioctls.
