Added support for firmware download for wcn6750. Changes done in detail: 1. Added regulators and corresponding current values. 2. Added sw_ctrl GPIO pin which is output from BT SoC and indicates status of clock supply to BT SoC. 3. Added inline function to check if the SoC type is wcn399x or wcn6750. 4. Modified the function qca_wcn3990_init() to support wcn6750 and renamed it to qca_regulator_init(). 5. Added BT_ON and BT_OFF macros. 6. Added support to download mbn type firmware image as wcn6750 supports mbn type image. 7. If mbn type image is not present then we will check for tlv type image. 8. Moved extracting rom version info to common place as this code is common in all if else ladder in qca_uart_setup.
