[PATCH v10 4/7] Bluetooth: hci_qca: Add wrapper functions for setting UART speed

2018-07-20 Thread Balakrishna Godavarthi
In function qca_setup, we set initial and operating speeds for Qualcomm
Bluetooth SoC's. This block of code is common across different
Qualcomm Bluetooth SoC's. Instead of duplicating the code, created
a wrapper function to set the speeds. So that future coming SoC's
can use these wrapper functions to set speeds.
