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

    | sdhci [sdhci_irq()]: *** mmc0 got interrupt: 0x00000001
    | mmc0: Timeout waiting for hardware interrupt.

Without this patch on rk3288 (dw_mmc-rockchip):

Rename quirks.c to quirks.h, and include it for
individual C files which need it.

mmc: core: Move public functions from card.h to private headers

A significant amount of functions and other definitions are available
through the public mmc card.h header file. Let's slim down this public mmc
interface, as to prevent users from abusing it, by moving some of the
functions/definitions to private mmc header files.

This change concentrates on moving the functions into private mmc headers,
following changes may continue with additional clean-ups.
