mmc: cmdq_hci: ice: Handle ICE HCI errors in cmdq mode
With ICE HCI addition in SDHC, couple of errors conditions
got introduced. These errors would be detected by ICE HCI and
triggers interrupt.
The two errors are:
1. Generic Crypto Error (GCE): This error is detected during the
transfer. Need to reset SDHC to recover.
2. Invalid Crypto Configuration Error (ICCE): The HW detects it
before the beginning of the transfer and terminates the transfer
before actual execution started.
Driver has to handle these error for recovering ICE-HCI from
these error conditions. This patch is for handling there errors
in cmdq mode.
