Remove 'file' parameter from struct machdep_calls.phys_mem_access_prot

The first two patches update fbdev and replace fbdev's fb_pgprotect()

Only PowerPC's fb_pgprotect() needs the file argument, although

Rename the fbdev mmap helper fb_pgprotect() to pgprot_framebuffer().

Add framer support in the fsl_qmc_hdlc driver in order to be able to
signal carrier changes to the network stack based on the framer status
Also use this framer to provide information related to the E1/T1 line
interface on IF_GET_IFACE and configure the line interface according to
IF_IFACE_{E1,T1}
The framer codec interacts with a framer.
It allows to use some of the framer timeslots as audio channels to
transport audio data over the framer E1/T1/J1 lines.
It also reports line carrier detection events through the ALSA jack
detection feature.

Introduce qmc_chan_{get,set}_ts_info() function to allow timeslots
modification at runtime.
The modification is provided using qmc_chan_set_ts_info() and will be
applied on next qmc_chan_start().
qmc_chan_set_ts_info() must be called with the channel rx and/or tx
stopped.

Timeslots setting is done at channel start() and stop().
There is no more need to do that during setup_chan().
Simply remove timeslot setting from setup_chan().

In order to support runtime timeslot route changes, some operations will

The QMC (QUICC mutichannel controller) is a controller present in some
