Subject: [PATCH] hisilicon-opensdk: bump to 2a38a27, so a CMA gk7205v500 can
 stream

OpenIPC/openhisilicon#238. dfc3a81..2a38a27 is exactly one commit.

With mmz_allocator=cma, the gk7205v500 default since #2526, a GK7205V510
panicked the kernel as soon as a bound VPSS channel delivered its first frame
to VENC. Nothing was printed, because the image keeps the console loglevel at
0, and the board rebooted panic= seconds later, so it looked like a hardware
reset. The closed venc object reads its bind descriptors with an unaligned
ldr.w (VENC_VpssSend+0x10f). osal's CMA allocator mapped non-cached MMBs
strongly-ordered, where that load faults in the VPSS interrupt. The carve-out
allocator's ioremap_wc() mapping is Normal non-cacheable, where it is legal.
osal now maps them write-combined, and also passes __dma_clear_buffer() the
coherent flag the kernel expects.
