Bin Meng 4957f668c4 hw/block: m25p80: Fix dummy byte handling for Spansion flash

Spansion flashes expose the number of dummy clock cycles through CR2V
register [1]. The value is a cycle count, not a byte count, so the
m25p80 model has to convert it to the number of whole SSI transfer
bytes consumed while collecting read command data.

Add a helper that multiplies the CR2V dummy cycle count by the phase
width and rounds up non-byte-aligned counts, matching the byte-oriented
SSI model. The default eight-cycle configuration keeps the same byte
counts as before.
