Removing default flow control for MTB_LAIRD_BL652

[ashok-rao]

Description

Flow control is enabled by default for this target that derives from nRF52. It needs to be disabled for the MTB_LAIRD_BL652 module target since this module does not need flow control enabled.

Verified with printf() messages on the serial terminal. WIth FC = "RTSCTS" (i.e. default in Mbed OS today) there are no debug messages sent over the UART to terminal.

@cmonr or @0xc0170 : Please let me know what tests would be required for this. I can attach relevant logs. Thanks.

Any test should do as would test the console uart

The default behavior is null so you can just remove the line completely like for the other targets that don't require flow control.
