This adds the missing kernel bits for Bluetooth support on the Tronsmart Vega S95 (GXBB based) boards as well as for the GXL P230/P231 and GXM Q200/Q201 reference boards. The Bluetooth functionality on these boards is provided by the SDIO wifi/Bluetooth combo-chip (Broadcom bcm43xx based). The Bluetooth module on that combo-chip has to be taken out of reset, which is taken care of the GPIO in the sdio_pwrseq. Once the module is taken out of reset it can be set up from userspace using the "hciattach" tool from bluez, which talks to the Bluetooth module which is connected to one of the serial ports (in our case uart_A). To get the Bluetooth module initialized within the timeout defined by "hciattach" (and to achieve usable speeds for Bluetooth transfers) the communication uses a speed of 2000000 baud, which was not supported by meson_uart before.
