ide-cs.c is the only PCMCIA device driver making use of CONFIG_PCMCIA_DEBUG,
so convert it to use the dynamic debug infrastructure.

Also, remove all usages of the CS_CHECK macro and replace them with proper
Linux style calling and return value checking. The extra error reporting may
be dropped, as the PCMCIA core already complains about any (non-driver-author)
errors.

thanks for your comment. And I see your point -- but as I intend to push this
upstream using the linux-pcmcia tree, as the IDE and ATA subsystems use the
same (linux-ide) mailing list, and as both drivers are quire related, I
thought handling both drivers in one patch is acceptable. If it still needs
to be done otherwise, I'll re-submit this patch in two parts and udpate my
workflow accordingly.

Best,
	Dominik

    Please submit as two separate patches as ide and libata are two separate 
subsystems.

WBR, Sergei
