dmaengine: stm32-mdma: Revert "dmaengine: stm32-mdma: Add a check on read_u32_array"

This reverts commit 906b40b246b0 ("dmaengine: stm32-mdma: Add a check on
read_u32_array")

As stated by bindings "st,ahb-addr-masks" is optional.
The statement inserted by this commit makes this property
mandatory and prevents MDMA to be probed in case property not present.
