Use the generic error number instead of meaningless value.

"host->version" isn't a SoC specific value.
It doesn't need to get in each SoC drivers.

This driver did not yet configure the SDHCI MBUS bridge registers.
Without this and with CONFIG_MMC_SDMA enabled, mmc hangs at random
times. As DMA cannot complete correctly.
Tested on db-88f6820-gp eval board.

Change addresses to unsigned long to be compatible with 64-bit builds.
Regardless of fixing warnings, the device is still only 32-bit capable.

Fix:
mv_sdhci.c: In function 'mv_sdh_init':
mv_sdhci.c:47:22: warning: the comparison will always
evaluate as 'true' for the address of 'mv_sdhci_writeb'
will never be NULL [-Waddress]

sdhci_readw does not work for host version read in Armada100 series
SoCs. This patch fix this issue by making a sdhci_readl call to get host
version.

Marvell 88SV331xV5 platform's sdhci host control is not very standard
with the spec in the 8bit handling. It need to set its private register
to switch to the 8bit mode which is not included in the standard sdhci
registers.
This patch mainly hacks the writeb method, and set its private register
if it find the driver is going to switch to the 8bit mode.

This could support both armada100 and pantheon serial in the mainline,
while this driver also be tested to support upcoming mg, mmp2 and mmp3
hardware.
