While adding support for the BCM4354, I discovered a few more things that weren't working as they should have. First, we disallow serdev from setting the baudrate on BCM4354. Serdev sets the oper_speed first before calling hu->setup() in hci_uart_setup(). On the BCM4354, this results in bcm_setup() failing when the hci reset times out. Next, we add support for setting the PCM parameters, which consists of a pair of vendor specific opcodes to set the pcm parameters. The documentation for these params are available in the brcm_patchram_plus package (i.e. https://github.com/balena-os/brcm_patchram_plus). This is necessary for PCM to work properly. All changes were tested with rk3288-veyron-minnie.dts.
