ASoC: bcm2835: Support additional samplerates up to 384kHz
Sample rates are only restricted by the capabilities of the clock driver, so use SNDRV_PCM_RATE_CONTINUOUS instead of SNDRV_PCM_RATE_8000_192000. Tests (eg with pcm5122) have shown that bcm2835 works fine in 384kHz/32bit stereo mode, so change the maximum allowed rate from 192kHz to 384kHz.
