Two off-by-one errors: INTSTAT0 missed BIT(31) and INTSTAT1 is only
defined on first 16 bits.

There is an assumption that the first two PDIs are reserved for Bulk,
so we need to make sure the number of bidir PDIs is indeed larger than
two. If the configuration provided is incorrect, this could lead to
allocating a huge amount of memory.

The Slave status mask exposes 4 sticky bits. When the device loses
sync, the IP will report two status but the log will only show that
the device lost sync. The status mask has all the information needed
so let's report it instead.
Also change the resolution of the mask, using 64 bits is not needed
when you need 4.

When commands start failing, e.g. due to a bad electrical connection
or bus conflicts, the dmesg log is flooded. This should not happen for
production devices but it's quite frequent when bringing-up a new
platform.

On arm64 the cadence_master.c file doesn't compile.
readl and writel are undefined.
This patch fixes that by including io.h.

Linux code style doesn't expect empty lines after braces and
gives warning:
CHECK: Blank lines aren't necessary after an open brace '{'
Remove the empty line in cadence lib
