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 v8:
    * updated soc_type with enum.

Changes in v7:
    * initial patch
    * redefined qca_uart_setup function to generic.

I thought we agreed in the discussion on "[v7,4/8] Bluetooth: btqca:
Redefine qca_uart_setup() to generic function" to call
qca_read_soc_version() in common code. Did I misinterpret that?
