hw/sd/sdhci: Block Size Register bits [14:12] is lost

Browse Source 
Block Size Register bits [14:12] is SDMA Buffer Boundary, it is missed
in register write, but it is needed in SDMA transfer. e.g. it will be
used in sdhci_sdma_transfer_multi_blocks to calculate boundary_ variables.

Missing this field will cause wrong operation for different SDMA Buffer
Boundary settings.

Fixes: d7dfca0807 ("hw/sdhci: introduce standard SD host controller")
Fixes: dfba99f17f ("hw/sdhci: Fix DMA Transfer Block Size field")
