New port: AIGO EROS Q / EROS K The Q and K have a slightly different case, but the hardware under the shell is completely identical. These models are rebadged versions: * Hifiwalker H2 (== Q) * AGPTek H3 (== K) * Surfans F20 (== K) Other notes: * Significant improvements in the shared Hiby-platform launcher/loader * SD card can theoretically be hot-swapped now * Support external USB mass storage! * Some consolidation of Hiby-platform targets * Some consolidation of plugin keymaps Todo/known issues: * Keymaps need to be gone over properly * Convert to HAVE_SCROLLWHEEL?

ErosQ (both): avoid clipping due to DC offset bandaid Set the maximum volume on both hosted and native ports to -2 dB. Verified behavior here on native and by borkitall on irc for hosted. Change-Id: I3aebc2bb4b9294a4137a33694c83139c0d76099a

/* a small DC offset prevents play/pause clicking due to the DAC auto-muting */
Eros Q Hosted: Apply DC Bias to PCM Data Similar to the native port, the hosted port benefits from adding a -1 dc bias to the PCM data. This prevents almost all clicking artifacts. Change-Id: Ic6378716774b6d88df23c476e2ef54d49f33dc72
