staging: rtl8192e: remove 5G related code

In previous patches we removed 5G code since the hardware that uses this
driver does not support 5G. There is still some 5G related code, remove it.
All the removed defines are unused and we can safely remove "N-5G" from the
rtllib_modes array.

staging: rtl8192e: Rework EEPROM handling code

Card configuration is stored in SPI EEPROM (93c46 or 93c56)
working in 128|256x16 mode.
Communication is handled using GPIO bitbang.

>From behaviour perspective, delay after read was removed.
It is not needed as we wait after reading GPIO mapped to
PCI-E register - it should have no side effects.

According to sample EEPROM datasheet (AT93Cx6), max frequency for
worst case scenario (1.8V supply) is 250kHZ (vs. 1MHz for 5V).
Driver generates ~50kHZ clock - margin should be big enough
even for devices from other vendors.

rtl8192e: Split into two directories

Now that the rtl8192e driver is split up, it makes sense to keep the
rtllib code in one directory and the rtl8192e specific code in
another. This patch contains the split and the fixup of includes.

Since rtl_core.h already included rtllib.h and dot11d.h, rtl_core.h
was updated to point to the parent directory. All other references to
rtllib.h and dot11d.h in the rtl8192e specific code where deleted
rather than fixed. This leaves just one file that needs to know the
real location of the rtllib includes.
