[E58][AUDIO] Adjust I2S audio output

Changes:

• Ported SECO TLV320 patches from NXP's kernel
• Skip internal clock setup if external PLL is active. MediaTek generates clock in the machine driver
• Add afe property to use same mclk for input and output
• Increase the mclk_fs_ratio to achieve a more common 12.2 MHz MCLK instead of default 6.1 MHz
• Removed processor specific sound card names. This way, we can define a carrier specific name in the carrier overlay. Alsa won't depend on the card name anymore
