2283284b05 ARM: keystone2: Add missing privilege ID settings
Add missing Privilege ID settings for KS2 SoCs.

Based on:
K2H/K: Table 6-7. Privilege ID Settings from SPRS866E (Nov 2013)
  http://www.ti.com/lit/ds/symlink/66ak2h14.pdf (page 99)
K2L: Table 7-7. Privilege ID Settings from SPRS930 (April 2015)
  http://www.ti.com/lit/ds/symlink/66ak2l06.pdf (page 71)
K2E: Table 7-7. Privilege ID Settings from SPRS865D (Mar 2015)
  http://www.ti.com/lit/ds/symlink/66ak2e05.pdf (page 75)
K2G: Table 3-16. PrivIDs from SPRUHY8 (Jan 2016)
  http://www.ti.com/lit/ug/spruhy8/spruhy8.pdf (page 238)

NOTE: Few of these might have default configurations, however,
since most are software configurable, it is better to explicitly
configure the system to have a known default state.

Without programming these, we end up seeing lack of coherency on certain
peripherals resulting in inexplicable failures (such as USB peripheral's
DMA data not appearing on ARM etc and weird workarounds being done by
drivers including cache flushes which tend to have system wide
performance impact).

By marking these segments as shared, we also ensure SoC wide coherency
is enabled.

1f807a9f32 ARM: keystone2: Refactor MSMC macros to avoid #ifdeffery
MSMC segment Privilege ID is not consistent accross the keystone2 SoCs.
As the first step to ensure complete SoC wide coherency setup, lets
refactor the macros to remove the #if-deffery around the code which
obfuscates which IDs are actually enabled for which SoC.

As a result of this change the PCIe configuration is moved after the
msmc configuration is complete, but that should ideally have no
functional impact.

use it instead of a hard-coded number in the code that
disables all the DSPs on various Keystone2 SoCs.

keystone platforms. If a PLL is not available, the corresponding
register addresses are marked as reserved.
Hence use a common definition.
