Alex Elder f60e5fb6df net: ipa: more include file cleanup 
All of the config data files and all of the register definition
files (plus a few others) use GSI_EE_AP, which is defined in
"ipa_version.h".  Include that header where it's needed.

All of the IPA register definition files include "../ipa.h", though
none of them need anything defined there.  Similarly, all of the GSI
register definition files include "../gsi.h", but don't need anything
defined there.  Remove these unnneded includes.

All of the configuration data files include "../gsi.h", though none
of them need anything defined there, so remove these includes.

Remove other includes of local header files that are not required.

/**
* DOC: IPA Registers
*
* IPA registers are located within the "ipa-reg" address space defined by
* Device Tree. Each register has a specified offset within that space,
* which is mapped into virtual memory space in ipa_mem_init(). Each
* has a unique identifer, taken from the ipa_reg_id enumerated type.
* All IPA registers are 32 bits wide.
*
* Certain "parameterized" register types are duplicated for a number of
* instances of something. For example, each IPA endpoint has an set of
* registers defining its configuration. The offset to an endpoint's set
* of registers is computed based on an "base" offset, plus an endpoint's
* ID multiplied and a "stride" value for the register. Similarly, some
* registers have an offset that depends on execution environment. In
* this case, the stride is multiplied by a member of the gsi_ee_id
* enumerated type.
*
* Each version of IPA implements an array of ipa_reg structures indexed
* by register ID. Each entry in the array specifies the base offset and
* (for parameterized registers) a non-zero stride value. Not all versions
* of IPA define all registers. The offset for a register is returned by
* reg_offset() when the register's ipa_reg structure is supplied;
* zero is returned for an undefined register (this should never happen).
*
* Some registers encode multiple fields within them. Each field in
* such a register has a unique identifier (from an enumerated type).
* The position and width of the fields in a register are defined by
* an array of field masks, indexed by field ID. Two functions are
* used to access register fields; both take an ipa_reg structure as
* argument. To encode a value to be represented in a register field,
* the value and field ID are passed to reg_encode(). To extract
* a value encoded in a register field, the field ID is passed to
* reg_decode(). In addition, for single-bit fields, reg_bit()
* can be used to either encode the bit value, or to generate a mask
* used to extract the bit value.
