kernel: bump to 3.10.32

firmware: Add config options to reduce pwm emissions
  pwm_sample_bits: default 11, valid from 8 to 11. Allows pwm clock to be reduced by lowering sample bit-width
  pwm_mode_pwm: default 0, when set will use pwm mode rather than pdm which will reduce high frequencies
firmware: Add dither to pwm audio

kernel: ASoc: Don't report S24_LE support, it produces white noise with xbmc

firmware: cleanup: prune some unused libs
kernel: Bump to 3.10.33

kernel: Enable SCSI Generic Kernel Support/Module
See: https://github.com/raspberrypi/linux/issues/540

firmware: When hotplug is absent, try reading the edid as a fallback. Only switch to composite if both fail
firmware: audio_render: add support for float samples and non-power-of-two channels

firmware: hdmi: Allow hdmi channel map to be overridden with a gencmd

firmware: audioplus: limit sample rates to ones supported by hardware

firmware: mailbox: Add property to get memory handle from dispmanx resource
See: https://github.com/raspberrypi/firmware/issues/257

firmware: Allow interrupts to be masked from GPU (e.g. when arm is handling them)
See: https://github.com/raspberrypi/firmware/issues/257

firmware: memory reduction of cutdown firmware (saves about 1M)
See: https://github.com/raspberrypi/linux/issues/503
