a29878553a ALSA: lx6464es - fix device communication via command bus
commit 6175ddf06b optimized the mem*io
functions that have been used to send commands to the device. these
optimizations somehow corrupted the communication with the lx6464es,
that resulted the device to be unusable with kernels after 2.6.33.

this patch emulates the memcpy_*_io functions via a loop to avoid these
problems.

the command buffer is only accessed from one file, so we can declare the
specific functions as static in that file

80b52490cd ALSA: lx6464es - include mac address in device name
each device has a unique mac address, which can be used to distinguish
multiple devices in the same machine. we therefore include the full mac
address in the device shortname and the last 6 bytes in the device id.
