soc: ixp4xx: qmgr: Pass resources
Instead of using hardcoded base address implicitly
obtained through <linux/io.h>, pass the physical base
for the QMGR block as a memory resource and remap
it in the driver.
Also pass the two IRQs as resources and obtain them
in the driver.
Use devm_* accessors and simplify the error path in the
process. Drop memory region request as this is done by
the devm_ioremap* functions.
