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.

Changes in v9:
* moved qca_read_soc_ver() to qca_setup().
Changes in v8:
* updated soc_type with enum.
Changes in v7:
* initial patch
* redefined qca_uart_setup function to generic.
