This patch series adds busy detect for stm32 sdmmc variant.
Some adaptations are required:
-Avoid to check and poll busy status when is not expected.
-Clear busy status bit if busy_detect_flag and busy_detect_mask are
 different.
-Add hardware busy timeout with MMCIDATATIMER register.

V2:
-mmci_cmd_irq cleanup in separate patch.
-simplify the busy_detect_flag exclude
-replace sdmmc specific comment in
"mmc: mmci: avoid fake busy polling in mmci_irq"
to focus on common behavior
