The present build configuration for the rtlwifi family of drivers will
fail under two known conditions:
(1) If rtlwifi is selected without selecting any of the dependent drivers,
there are errors in the build.
(2) If the PCI drivers are built into the kernel and the USB drivers are modules,
or vice versa, there are missing globals.
The first condition is fixed by never building rtlwifi unless at least one
of the device drivers is selected. The second failure is fixed by splitting
the PCI and USB codes out of rtlwifi, and creating their own mini drivers.
If the drivers that use them are modules, they will also be modules.
Although a number of files are touched by this patch, only Makefile and Kconfig
have undergone significant changes. The only modifications to the other files
were to export entry points needed by the new rtl_pci and rtl_usb units, or to
rename two variables that had names that were likely to cause namespace collisions.

Commit a269913c5 entitled "rtlwifi: Rework rtl_lps_leave() and
rtl_lps_enter() to use work queue" has two bugs for USB drivers.
Firstly, the work queue in question was not initialized. Secondly,
the callback routine used by this queue is contained within the
file used for PCI devices. As a result, it is not available for
architectures without PCI hardware.

Adding casts of objects to the same type is unnecessary
and confusing for a human reader.
For example, this cast:
int y;
int *p = (int *)&y;
I used the coccinelle script below to find and remove these
unnecessary casts. I manually removed the conversions this
script produces of casts with __force, __iomem and __user.

This patch addresses a kernel bugzilla report and two recent mail threads.
The kernel bugzilla report is https://bugzilla.kernel.org/show_bug.cgi?id=42632,
which reports a udev timeout on boot.
The first mail thread, which was on LKML (http://lkml.indiana.edu/hypermail/
linux/kernel/1112.3/00965.html) was for a WARNING that occurs after a
suspend/resume cycle for rtl8192cu.
The scond mail thread (http://marc.info/?l=linux-wireless&m=132655490826766&w=2)
concerned changes in udev that break drivers that delay while firmware is loaded
on modprobe.
This patch converts all rtlwifi-based drivers to use the asynchronous firmware
loading mechanism. Drivers rtl8192ce, rtl8192cu and rtl8192de share a common
callback routine. Driver rtl8192se needs different handling of the firmware,
thus it has its own code.

With previous patch "rtlwifi: use work for lps" we can now use mutex for
protecting ps mode changing critical sections. This fixes running system
with interrupts disabled for long time.
Merge ips_lock and lps_lock as they seems to protect the same data
structures (accessed in rtl_ps_set_rf_state() function).
