Tomas Winkler 24aadc809f mei: don't query HCSR for host buffer depth
1. We record host (write) buffer depth during reset
 so we don't need to query HCSR register later on.
 The host buffer depth doesn't change after the reset
2. Use mei_hbuf_max_data function to compute payload size in bytes

Greg Kroah-Hartman ffc2825c29 Staging: mei: move the mei code out of staging
It's been cleaned up, and there's nothing else left to do, so move it
out of staging into drivers/misc/ where all can use it now.
