2d9fecf428 Add table driven way to add platform specific reg_script routines
Extend lib/reg_script.c to use a platform table to declare
additional platform specific register access routine functions.
REG_SCRIPT_TYPE_PLATFORM_BASE is the starting value for platform
specific register types.  Additional register access types may be
defined above this value.  The type and access routines are placed
into reg_script_type_table.

The Baytrail type value for IOSF was left the enumeration since it
was already defined and is being used for Braswell.

BRANCH=none
BUG=None
TEST=Use the following steps to test:
1.  Build for a Baytrail platform
2.  Build for the Samus platform
3.  Add a platform_bus_table routine to a platform which returns the
    address of an array of reg_script_bus_entry structures and the
    number of entries in the array.

These have apparently never been used because they are
incorrect.

9ed77718c7 reg_script: add reg_script_run_on_dev()
The reg_script library has proven to be useful. It's
also shown that many scripts operate on devices. However,
certain code paths run the same script on multiple,
but different, devices. In order to make that easier
introduce reg_script_run_on_dev() which takes a device
as a parameter. That way, chained reg_scripts are not
scrictly needed to run the same script on multiple devices.

BUG=None
BRANCH=None
TEST=Built.

6178e16ab7 regscript: Add support for MSR type
This required changing value/mask types to uint64_t.

Another option would be to use id field to select low or high
32 bits of the MSR and set them independently.

49150a1494 Add a generic register script handler
This is based on the RCBA configuration setup from haswell.
It handles PCI, BARs, IO, MMIO, and baytrail-specific IOSF.
I did not extend it to handle MSR yet but that would be another
potential register type.

There are a number of approaches to this kind of thing, but in the
end they have a lot of switch statements and a mass of #defines.
I'm not particularly set on any of the details so comments welcome.
