ASoC: Intel: sof_rt5682: Add ALC1015Q-VB speaker amp support

This patch adds jsl_rt5682_rt1015p which supports the RT5682 headset
codec and ALC1015Q-VB speaker amplifier combination on JasperLake
platform.

This driver also supports ALC1015Q-CG if running in auto-mode.
Following table shows the audio interface support of the two
amplifiers.

          | ALC1015Q-CG | ALC1015Q-VB
=====================================
I2C       | Yes         | No
Auto-mode | 48K, 64fs   | 16k, 32fs
                        | 48k, 32fs
                        | 48k, 64fs
