A driver may be included even when there is no associated core
present. (See the DEPENDS option in data/*.mdd).
If another driver includes this TmrCtr driver, despite no
associated timer counter core existing, then xtmrctr.tcl won't be
invoked by SDK and the xtmrctr_g.c will not be generated.
If this file is not generated, the BSP will include the default
xtmrctr_g.c which was previously assuming that there is at least
one instance of the core in the system.
Also, the XPAR_XTMRCTR_NUM_INSTANCES wasn't being defined in this
case.
Protection against such a scenario is required.
Some subsystem drivers will include all subcore drivers,
regardless whether they are a part of the system or not.

To prevent unexpected behavior resulting from jumping to a NULL
address.
Previously, if the user didn't define a callback before the
occurence of an interrupt, the driver's interrupt handler would have
invoked a function pointer to NULL.

Added configuration initialization and hardware initialization API
functions.
The XTmrCtr driver is now consistent with other drivers.
The previous initialization structure disallowed using a different
base address from what was found in the xparameters and the
configuration table of the core.
The XTmrCtr_Initialize function was overriding the effective base
address internal to the core - it still as to keep the API
functionality intact for backward-compatibility.
Internally, the function is calling the new APIs.
This poses an issue if the memory addresses have been translated
differently from the physical base address.
Also, such as is for subsystem drivers, the base address of one
of the subsystem's subcores will appear as a relative offset to
the base address of the subsystem.
This issue is addressed by providing the higher level with control
of which base address will be used by the driver.
