pcmcia: simplify Status, ExtStatus register access

The Status (CISREG_CCSR) and ExtStatus (CISREG_ESR) registers were
only accessed to enable audio output for some drivers and IRQ for
serial_cs.c. The former also required setting config_req_t.Attributes
to CONF_ENABLE_SPKR; the latter can be simplified to setting this
field to CONF_ENABLE_ESR.
