lpc43/54 SDMMC: Wading through bits trying to make sense out of what is a event want interrupt which deal mostly with commands+responses and what is a data transfer event. DTO is the only wildcard. I think this clear now but DMA transfers will fail with CRC error.
lpc43/54 SDMMC: DTO is a wait event, not a transfer event.
lpc43/54 SDMMC: Significant simplication to previous design. More debug output.
lpc43/54 SDMMC: Don't allow duplicate events in waitmask and xfrmask.
lpc43/54 SDMMC: Not all interrupts were being disabled at the end of a transfer.
lpc43/54 SDMMC: Defer enabling DMA transfer interrupts until after command has been sent.
Squashed commit of the following:
arch/arm/src/lpc43xx: SDMMC driver now builds for the LPC43 (provided that the proper definitions appear in the board.h file).
arch/arm/src/lpc43xx: Update basic changes to the ported lpc54xx driver for lpc43xx clocking and GPIOs.
arch/arm/src/lpc43xx: Brings in the LPC54xx SD/MMC driver with absolutely no changes other than changing all occurences of 54 to 43.
arm/arm/src/lpc43xx: Add build support for the lpc54 SDMMC driver.
lpc54 SDMMC: Check for successful data transfer last. Checking first means that we miss errors.
Squashed commit of the following:
arch/arm/src/lpc54xx: SDMMC fixes.. DMA should not be enabled on non-DMA transfers, the burst setting in FIFOTH is supposed to match the burst setting in the BMOD reseters, Add DMA error interrupt support.
arch/arm/src/lpc54xx: Mostly costmetic changes to the SDMMC driver.
In ARM document regarding memory barrires, SP_DMB() must be issued
before changing a spinlock state to SP_UNLOCKED. However, we found
that SP_DSB() is also needed to ensure that spin_unlock() works
correctly for network streaming aging test.

In lc823450, ldrex and strex are not supported. So we implemented
up_testset() with H/W Mutex. However, there was a bug in memory
access order. This change ensures correct memory access order in
up_testset() for lc823450.
