mmc: sdhci: use lower/upper_32_bits() macros for DMA addresses

Browse source

Currently, the DMA addresses are casted to (u64) for the upper 32bits
to avoid "right shift count >= width of type" warning.

<linux/kernel.h> provides macros to address this, and I like the macro
names are self-documenting.

I introduced a new helper, sdhci_set_adma_addr() to avoid the code
duplication.
