Adapt DRMKMS BUILD_BUG_ON_MSG() to static_assert semantics

static_assert is violated with runtime-only compiler semantics in a few

provide BUILD_BUG_ON_MSG

don't provide dev_to_i915 and ifdef out all users (unused)
provide nsecs_to_jiffies64, hopefully msec_to_jiffies * 10^6
provide BUILD_BUG as a no-op
include linux/err.h instead of matching side-loading, too hard to
figure out what gets it.

memset_io doesn't need to return anything.

Previous change to make argument volatile broke return, but we don't
need it anyway.

Allow memset_io &c. to take volatile.

memset_io works with bytes not dwords, noted by riastradh@

Don't use memset as memset_io on aarch64. With c=0 it uses the "dc zva"
cache maintenance instruction as an optimization which does not work on
device memory.

linux asm/uaccess.h: strncpy_from_user

(which does not actually have strncpy semantics, naturally, from what
I can gather)

drm: Another pass over i915 and some supporting logic.

This makes a shim around sg_table, which essentially represents two
things:

1. an array of pages (roughly corresponding to bus_dma_segment_t[])
2. an array of DMA addresses stored in a bus_dmamap_t

Both parts are optional; different parts of i915 use sg_tables to
pass around one or both of the two parts. This helps to reduce the
ifdefs by quite a bit, although it's not always clear which part of
an sg_table any particular interface is actually using which is why I
was reluctant to do this before.

Safe unsafe uaccess stubs.
