Christoph Fritz 91516a2a47 mmc: core: apply NO_CMD23 quirk to some specific cards 
To get an usdhc Apacer and some ATP SD cards work reliable, CMD23 needs
to be disabled.  This has been tested on i.MX6 (sdhci-esdhc) and rk3288
(dw_mmc-rockchip).

Without this patch on i.MX6 (sdhci-esdhc):

 $ dd if=/dev/urandom of=/mnt/test bs=1M count=10 conv=fsync

    | <mmc0: starting CMD23 arg 00000400 flags 00000015>
    | mmc0: starting CMD25 arg 00a71f00 flags 000000b5
    | mmc0:     blksz 512 blocks 1024 flags 00000100 tsac 3000 ms nsac 0
    | mmc0:     CMD12 arg 00000000 flags 0000049d
    | sdhci [sdhci_irq()]: *** mmc0 got interrupt: 0x00000001
    | mmc0: Timeout waiting for hardware interrupt.

Without this patch on rk3288 (dw_mmc-rockchip):

    | mmc1: Card stuck in programming state! mmcblk1 card_busy_detect
    | dwmmc_rockchip ff0c0000.dwmmc: Busy; trying anyway
    | mmc_host mmc1: Bus speed (slot 0) = 400000Hz (slot req 400000Hz,
    | actual 400000HZ div = 0)
    | mmc1: card never left busy state
    | mmc1: tried to reset card, got error -110
    | blk_update_request: I/O error, dev mmcblk1, sector 139778
    | Buffer I/O error on dev mmcblk1p1, logical block 131586, lost async
    | page write
