ALSA: ctxfi: Add support for Onkyo SE-300PCIE (OK0010)

Add support for the Onkyo SE-300PCIE, a Creative X-Fi CA20K2-based
sound card with a custom hardware implementation that differs
significantly from other CA20K2-based variants.

Changes:
 - PCI quirk entry for OK0010
 - Port 0x3 is utilized for dedicated RCA output (configured as I2S)
 - Modified GPIO pin mappings and states
 - 4-channel simultaneous ADC input support for line and microphone
   capture without input switching (similar to SB1270)
 - Simplified ADC initialization (no manual setup required)
