can: remove obsolete PCH CAN driver

Browse Source 
The PCH CAN driver is a driver for a Bosch C_CAN controller IP core which
is attached to the system via PCI. This code has been introduced in 2011
by Oki Semiconductors developers to support the Intel Atom E6xx series
I/O Hub (aka EG20T IOH PCH CAN). Since 2012 the driver only has been
maintained by the kernel community.

As there is a well maintained and continously tested C_CAN/D_CAN driver
which also supports the PCI configuration from the PCH CAN EG20T setup
this driver became obsolete.
