Without this additional delay, some eMMC don't negotiate properly bus width
Tested on:
- Toshiba THGBM2G8D8FBAIB
- Toshiba THGBM4G4D1HBAR
- Micron MTFC4GMVEA (the one giving the problem)
- Hynix H26M64002BNR
- SanDisk SDIN5E1-32G

Check for card detect each time an MMC/SD device is initialized. If card
detection is not implemented, this code behaves as before and continues
assuming a card is present. If no card is detected, has_init is reset
for the MMC/SD device (to force initialization next time) and an error
is returned.

Make existing field b_max field in struct mmc unconditional
and use it instead of CONFIG_SYS_MMC_MAX_BLK_COUNT in mmc_bread
and mmc_bwrite.
Initialize b_max to CONFIG_SYS_MMC_MAX_BLK_COUNT in mmc_register
if it has not been initialized by the hw driver.
Initialize b_max to 0 in all callers to mmc_register.

Added support for MMC/SD cards for Davinci. This feature is enabled by
CONFIG_DAVINCI_MMC and is dependant on CONFIG_MMC and CONFIG_GENERIC_MMC
options. This is tested on DM355 and DM365 EVMs with both the available mmc
controllers.
