The DVB framework will try to power-down an adapter that no-one is using
any more, but this assumes that the adapter is still connected to the
machine. That's not always true for a USB adapter, so disable the sleep
operations when the adapter has been physically unplugged.

This prevents I2C write failures with error -19 from appearing
occasionally in the dmesg log.

Usage of these flags has been deprecated for nearly 4 years by:

    commit f77bf014
    Author: Sam Ravnborg <sam@neptun.(none)>
    Date:   Mon Oct 15 22:25:06 2007 +0200

        kbuild: introduce ccflags-y, asflags-y and ldflags-y

Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command
line use. By default, gmake(1) do not override command line setting, so this is
likely to result in build failure or unexpected behavior.

Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

There were a several problems in this function:

1) Potential integer overflow in the comparison:
	if (fio.write_len + fio.read_len > 1028) {

2) If the user gave bogus values for write_len and read_len then
   returning -EINVAL is more appropriate than returning -ENOMEM.

3) wbuf was set to the address of an array and could never be NULL
   so I removed the pointless NULL check.

4) The call to vfree(wbuf) was improper.  That array is part of a
   larger struct and isn't allocated by itself.

5) flashio() can't actually fail, but we may as well add error
   handling in case this changes later.

6) In the default case where an ioctl is not implemented then
   returning -ENOTTY is more appropriate than returning -EFAULT.

This patch implements an i2c_gate_ctrl op for the cxd2820r. Thanks to Robert
Schlabbach for identifying the register address and field to set.

The old i2c intercept code that prefixed messages with a passthrough byte has
been removed and the PCTV nanoStick T2 290e entry in em28xx-dvb has been
updated appropriately.

Tested for DVB-T2 use; I would appreciate it if somebody with DVB-C capabilities
could test it as well - from inspection I cannot see any problems.

This is patch v2. It fixes some schoolboy style errors and removes superfluous
i2c entries in cxd2820r.h.
