The flash write protect pin is currently named 'FW_WP_AP', which is
how the signal is called in the schematics. The Chrome OS ABI
requires the pin to be named 'AP_FLASH_WP_L', which is also how
it is called on all other veyron devices. Rename the pin to match
the ABI.

Simplify and fix the version information displayed by the driver.
The new info better relects what is needed to support the hardware.
Prev:
Version: 4.8.0, Pipeline 22169 0x4001, Rev 0, Bond 5, CSR 311, IRQ 2
New:
Version: 4.8.0, Id: 0x4001 Hw Rev: 5 OTP Config Select: 15
- Remove pipeline, CSR and IRQ because version x.y.z already incorporates
this information.
- Remove bond number because it is not used.
- Remove rev number because register was not implemented, always 0
- Add HW Rev ID register to replace rev number
- Add OTP config select to show the user configuration chosen by
the configurable GPIO pins on start-up

/dev/random and getrandom() never warn. Split the meat of
urandom_read() into urandom_read_nowarn() and leave the warning code
in urandom_read().
This has no effect on kernel behavior, but it makes subsequent
patches more straightforward. It also makes the fact that
getrandom() never warns more obvious.

Make sure the NIC drops packets that are larger than the
specified MTU.
The front end of the NIC will accept packets larger than MTU and
will copy all the data it can to fill up the driver's posted
buffers - if the buffers are not long enough the packet will
then get dropped. With the Rx SG buffers allocagted as full
pages, we are currently setting up more space than MTU size
available and end up receiving some packets that are larger
than MTU, up to the size of buffers posted. To be sure the
NIC doesn't waste our time with oversized packets we need to
lie a little in the SG descriptor about how long is the last
SG element.
At dealloc time, we know the allocation was a page, so the
deallocation doesn't care about what length we put in the
descriptor.
