It is trivial to relax the restriction and permit read/write access.

usb: gadget: Allow to build both USB functions and legacy gadgets

Currently it is possible to build in some subset of usb functions
*OR* some gadget module. This is limited only by Kconfig not
any functionality.

This patch removes this limitation. With this patch it is possible
to set up all build combinations:
1) Multiple gadgets build in
2) Part of functions build in, part of functions as a modules
3) Some gadgets build in and some part of functions build in/modules
etc.

As this patch makes Kconfig quite complicated let me clarify how it works:

USB_F_<func name> - used in makefile for compilation
USB_CONFIGFS_F_<func name> - Chosen by user in function menu
USB_G_<gadget name>_REQ_F_<func name> - set up by gadget to mark
      that this particular gadget requires this func to work
USB_F_<func name>_SELECTOR - helper config which is used to determine
    if function should be build in or compiled as a module

The rules are quite simple:
1) If any of USB_CONFIGFS_F_<func name>, USB_G_*_REQ_F_<func name> equals
y, then USB_F_<func name> is set to y and function is build in
2) If none of USB_CONFIGFS_F_<func name>, USB_G_*_REQ_F_<func name> equals
y, but any of them equals m then USB_F_<func name> is set to m and function
is compiled as a module

panic: release stale console lock to always get the logbuf printed out

In some cases we may end up killing the CPU holding the console lock
while still having valuable data in logbuf. E.g. I'm observing the
following:

- A crash is happening on one CPU and console_unlock() is being called on
  some other.

- console_unlock() tries to print out the buffer before releasing the lock
  and on slow console it takes time.

- in the meanwhile crashing CPU does lots of printk()-s with valuable data
  (which go to the logbuf) and sends IPIs to all other CPUs.

- console_unlock() finishes printing previous chunk and enables interrupts
  before trying to print out the rest, the CPU catches the IPI and never
  releases console lock.

This is not the only possible case: in VT/fb subsystems we have many other
console_lock()/console_unlock() users.  Non-masked interrupts (or
receiving NMI in case of extreme slowness) will have the same result.
Getting the whole console buffer printed out on crash should be top
priority.

Android MM N910S kernel uses only pmic rtc, not rtc-s3c so i think it's
better to disable rtc-s3c.
