Subject: [PATCH 0/4] Bluetooth: hci_bcm: Additional changes for BCM4354 support

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.
