Reduce the logging from info to debug. Also use print_hex_dump_bytes
instead as it has support for dynamic printk providing options to
conditionally enable/disable these logs.

Underscores are usually forbidden in the compatible strings. So lets
remove it before the first users of this is seen.

This mailbox-test driver was designed to be generic, so let's remove ST
tag on it and make it generic.

Don't pass mmio region as source to print_hex_dump() and then
again to memcpy_fromio(). Do it once and give print_hex_dump()
the buffer we just read the data in.

We need to leave space for the NUL char.

Kbuild test robot reported some Sparse warnings to the tune of:
sparse: incorrect type in argument 6 (different address spaces)
expected void const *buf
got void [noderef] <asn:2>*mmio
This was due to passing variables tagged with the Sparse cookie
'__iomem' through into memcpy() and print_hex_dump() without
adequate protection or casting. These issues were fixed in a
previous patch suppressing the warnings, but the issue is indeed
still present.
This patch fixes the warnings in the correct way, i.e. by using
the purposely authored memcpy_{from,to}io() derivatives in the
memcpy() case and casting the memory address to (void *) and
forcing Sparse to ignore to ignore it in the print_hex_dump()
case [NB: This is also what the memcpy() derivatives do].

This particular Client implementation uses shared memory in order
to pass messages between Mailbox users; however, it can be easily
hacked to support any type of Controller.
