mmc: sdhci-of-arasan: Omit superfluous error messages

sdhci_add_host and sdhci_platfm_init already report failure,
so don't emit error messages when a failure occurs. This prevents
occurences of "deferred" messages when required power supplies
are not ready for operation yet.

mmc: sdhci-of-arasan: Use signed formatting in error messages

"ret" is a signed int, so use "%d" in format strings instead of "%u".
This prevents cryptic codes in error messages like this:

This patch removes unitstd32.h include to avoid duplication of
"__NR_" syscall definitions.

This patch is based on AOSP commit: cfc7e99e9e3900056028a7d90072e9ea0d886f8d,
"arm64: Add __NR_* definitions for compat syscalls", which adds
__NR_* definitions to asm/unistd32.h, moves the __NR_compat_*
definitions to asm/unistd.h and removes all the explicit unistd32.h
includes apart from the one building the compat syscall table.
The aim is to have the compat __NR_* definitions available but
without colliding with the native syscall definitions (required
by lib/compat_audit.c to avoid duplicating the audit header files
between native and compat).

Because in SMP, "mrq" has race condition between below two paths:
path1: CPU0: <tasklet context>
  static void mmc_wait_data_done(struct mmc_request *mrq)
  {
    mrq->host->context_info.is_done_rcv = true;
    //
    // If CPU0 has just finished "is_done_rcv = true" in path1, and at
    // this moment, IRQ or ICache line missing happens in CPU0.
    // What happens in CPU1 (path2)?
    //
    // If the mmcqd thread in CPU1(path2) hasn't entered to sleep mode:
    // path2 would have chance to break from wait_event_interruptible
    // in mmc_wait_for_data_req_done and continue to run for next
    // mmc_request (mmc_blk_rw_rq_prep).
    //
    // Within mmc_blk_rq_prep, mrq is cleared to 0.
    // If below line still gets host from "mrq" as the result of
    // compiler, the panic happens as we traced.
    wake_up_interruptible(&mrq->host->context_info.wait);
  }

path2: CPU1: <The mmcqd thread runs mmc_queue_thread>
 static int mmc_wait_for_data_req_done(...
 {
    ...
    while (1) {
          wait_event_interruptible(context_info->wait,
                  (context_info->is_done_rcv ||
                   context_info->is_new_req));

  static void mmc_blk_rw_rq_prep(...
  {
    ...
    memset(brq, 0, sizeof(struct mmc_blk_request));

This issue happens very coincidentally; however adding mdelay(1) in
mmc_wait_data_done as below could duplicate it easily.
  static void mmc_wait_data_done(struct mmc_request *mrq)
  {
    mrq->host->context_info.is_done_rcv = true;
    mdelay(1);
    wake_up_interruptible(&mrq->host->context_info.wait);
  }
At runtime, IRQ or ICache line missing may just happen at the same place
of the mdelay(1).

This patch gets the mmc_context_info at the beginning of function, it can
avoid this race condition.
