Nishanth Menon 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.
