Bluetooth: btqca: Redefine qca_uart_setup() to generic function.
Redefinition of qca_uart_setup will help future Qualcomm Bluetooth SoC, to use the same function instead of duplicating the function. Added new arguments soc_type and soc_ver to the functions. These arguments will help to decide type of firmware files to be loaded into Bluetooth chip. soc_type holds the Bluetooth chip connected to APPS processor. soc_ver holds the Bluetooth chip version.
