net: ipa: start creating GSI register definitions

Create a new register definition file in the "reg" subdirectory,
and begin populating it with GSI register definitions based on IPA
version. The GSI registers haven't changed much, so several IPA
versions can share the same GSI register definitions.

As with IPA registers, an array of pointers indexed by GSI register ID
refers to these register definitions, and a new "regs" field in the
GSI structure is initialized in gsi_reg_init() to refer to register
information based on the IPA version (though for now there's only
one). The new function gsi_reg() returns register information for
a given GSI register, and the result can be used to look up that
register's offset.

This patch is meant only to put the infrastructure in place, so only
eon register (CH_C_QOS) is defined for each version, and only the
offset and stride are defined for that register. Use new function
gsi_reg() to look up that register's information to get its offset,
This makes the GSI_CH_C_QOS_OFFSET() unnecessary, so get rid of it.

net: ipa: add per-version IPA register definition files

Create a new subdirectory "reg", which contains a register
definition file for each supported version of IPA. Each register
definition contains the register's offset, and for parameterized
registers, the stride (distance between consecutive instances of the
register). Finally, it includes an all-caps printable register name.

In these files, each IPA version defines an array of IPA register
definition pointers, with unsupported registers defined with a null
pointer. The array is indexed by the ipa_reg_id enumerated type.

At initialization time, the appropriate register definition array to
use is selected based on the IPA version, and assigned to a new
"regs" field in the IPA structure.

Extend ipa_reg_valid() so it fails if a valid register is not
defined.

This patch simply puts this infrastructure in place; the next will
use it.
