2. invalidate buffer cache on demand
3. reduce scantimer interval to 100us

This reverts commit 75b31192fe.
The original purpose of customized pcm was to config prealloc buffer size
flexibly. but, we can do the same thing by soc-generic-dmaengine-pcm.
And the generic one can generated the better config by querying DMA
capabilities from dmaengine driver rather than the Hard-Coded one.
e.g.
the customized one:
static const struct snd_pcm_hardware snd_rockchip_hardware = {
.info = SNDRV_PCM_INFO_MMAP |
SNDRV_PCM_INFO_MMAP_VALID |
SNDRV_PCM_INFO_PAUSE |
SNDRV_PCM_INFO_RESUME |
SNDRV_PCM_INFO_INTERLEAVED,
...
the generic one:
ret = dma_get_slave_caps(chan, &dma_caps);
if (ret == 0) {
if (dma_caps.cmd_pause && dma_caps.cmd_resume)
hw.info |= SNDRV_PCM_INFO_PAUSE | SNDRV_PCM_INFO_RESUME;
if (dma_caps.residue_granularity <= DMA_RESIDUE_GRANULARITY_SEGMENT)
hw.info |= SNDRV_PCM_INFO_BATCH;
...
So, let's revert back to use the generic dmaengine pcm.

Currently, The fixed 512KB prealloc buffer size is too larger for
tiny memory kernel (such as 16MB memory). This patch adds the module
option "prealloc_buffer_size_kbytes" to specify prealloc buffer size.
It's suitable for cards which use the generic dmaengine pcm driver
with no config.

Add a new drm_connector_oob_hotplug_event() function and
oob_hotplug_event drm_connector_funcs member.
On some hardware a hotplug event notification may come from outside the
display driver / device. An example of this is some USB Type-C setups
where the hardware muxes the DisplayPort data and aux-lines but does
not pass the altmode HPD status bit to the GPU's DP HPD pin.
In cases like this the new drm_connector_oob_hotplug_event() function can
be used to report these out-of-band events.
Avoid the conflict of GKI, the drm_connector_oob_hotplug_event() is be
completed in rockchip drm driver, not the drm framework.
