[ Upstream commit f904feefe60c28b6852d5625adc4a2c39426a2d9 ]
Add support for the Bluetooth chip codenamed APACHE which is part of WCN3988.
The firmware for this chip has a slightly different naming scheme compared to most others. For ROM Version 0x0200 we need to use apbtfw10.tlv + apnv10.bin and for ROM version 0x201 apbtfw11.tlv + apnv11.bin
