Store in interrupt service routine always '1' in end_command, not the
value of host->cmd to fix compile test warnings on RISC-V:
drivers/mmc/host/davinci_mmc.c:999:17: warning:
cast from pointer to integer of different size [-Wpointer-to-int-cast]

iomem pointers should be printed with pointer format to hide the
actual value and fix warnings when compile testing for 64-bit

Since driver data is a pointer, direct casting to integer causes
warning when compile testing for 64-bit architecture:
drivers/mmc/host/s3cmci.c:1495:17: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
The actual driver data can be only 0 or 1, so cast it via long and do
not care about any loss of value.
