[PATCH v3 08/14] hw/dma/zynq-devcfg: Fix register memory

["Corvin Köhne" <corvin.koehne@gmail.com>]

From: YannickV <Y.Vossen@beckhoff.com>

Registers are always 32 bit aligned. R_MAX is not the maximum
register address, it is the maximum register number. The memory
size can be determined by 4 * R_MAX.

Currently every register with an offset bigger than 0x40 will be
ignored, because the memory size is set wrong. This effects the
MCTRL register and makes it useless. This commit restores the
correct behaviour.
