[PATCH v1 3/3] hciattach: Enable loading BCM43xx firmware on RPi

[Dave Jones <dave.jones@canonical.com>]

Corrects the location of the firmware from /etc/firmware to
/lib/firmware, and disables setting the UART interface speed prior to
loading the firmware. An already existing later call to
bcm43xx_set_speed still sets the speed of the interface as requested.

For certain bluetooth devices, in particular that on the Raspberry Pi
400, setting the UART speed prior to loading the firmware causes the
firmware load to fail.
