properly anyway.  I have no method of reseting the core to a working state at
this time; but I didn't try too hard to work one out either.  The problem
likely only occurs in development.  I suspect configuring the SYS PLL VCO to
oscillate too slowly (286.3 MHz?) before post divide may be the root cause,
when encountered.

V4L/DVB (13086): cx23885: Add skeleton v4l2_subdev for the CX23888 integrated IR controller

This change adds a skeletal implementation of a v4l2_subdevice to provide
encapsulation and abstraction of the CX23888's integrated consumer infrared
controller.  This change also instantiates the cx23888_ir subdev for the
HVR-1850 which has IR hardware physically wired up to a CX23888.

The cx23888_ir subdev code is being written with long-term objectives to:
1. port it to the cx25840 module for the CX2584x, CX2583x, CX23885, & CX231xx
   IR controllers
2. possibly port it to the cx18 module for the CX23418 IR controller
3. have the IR subdevice accessed abstractly in the cx23885 module, so the
   driver can ignore the difference between the CX23885 and CX23888.

V4L/DVB (13085): cx23885: Fix support for v4l2-dbg access to CX2388[578] and CX23417 regs

This changes corrects the ioctl() operations for both the CX2388[578] analog
video and MPEG video device nodes to properly and consistently support
VIDIOC_G_CHIP_IDENT, VIDIOC_DBG_G_REGISTER and VIDIOC_DBG_S_REGISTER ioctl()s.

This caused some ioctl() support routines to be broken out into a separate
source file.

Now v4l2-dbg can be used to manipulate CX2388[578] and CX23417 registers
including the CX2388[57] functions handled by the cx25840 module.

This was done in anticipation of developing a new v4l2_subdev for the
integrated IR controller of the CX23888.
