counter: new TI eQEP driver
This adds a new counter driver for the Texas Instruments Enhanced Quadrature Encoder Pulse (eQEP) module. Only very basic functionality is currently implemented - only enough to be able to read the position. The actual device has many more features which can be added to the driver on an as-needed basis. It is not possible to read the QEPA/B signal values in hardware, so that feature is omitted. The TI_PWMSS kernel option is selected in Kconfig to enable the parent bus, which is needed for power management.
