Some devices need to clear the fb panbuf when waking up from sleep
to avoid outputting residual buffers from before sleeping

when the vsync comes, fb drivers should call fb_vsync_pollnotify to notify POLLPRI, so that users can catch the synchronization time of vsync and do something.

so the user could register fb device directly instead
go through the sequence of up_fbinitialize/up_fbgetvplane

1. support doublebuffer swtich for overlay layer
2. Add display area ioctl to scale the active area of the overlay layer
to a specific region on the LCD through hardware.

Considering that the future fb needs to achieve dynamic resolution, the address and size of fbmem will be redistributed on the bottom driver side, so remove fbmem, fblen, and bpp cached in fb_chardev_s, and change it to call getplaneinfo every time to re-acquire panel info from the bottom driver. Avoid cache coherency problems.

When executing up_fbinitialize, the driver may turn on the vsync interrupt. If the vsync interrupt calls fb_pollnotify before executing fb->vtable->priv = fb it will cause null pointer access and crash.

since mmap may exist in block_operations, but truncate may not,
moving mmap beforee truncate could make three struct more compatible

* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
