docs/specs/aspeed-intc: Remove GIC 128 - 136
The GIC interrupts 128 - 136 were only used by the AST2700 A0 SoC.
Since the AST2700 A0 has been deprecated, these interrupt
definitions are no longer needed. This commit removes them to
clean up the codebase.

-AST2700 A0
-----------
-It has only one INTC controller, and currently, only GIC 128-136 is supported.
-To support both AST2700 A1 and AST2700 A0, there are 10 OR gates in the INTC,
-with gates 1 to 9 supporting GIC 128-136.
-
-Design for GICINT 132
----------------------
-The orgate has interrupt sources ranging from 0 to 31, with its output pin
-connected to INTC. The output pin is then connected to GIC 132.
