firmware: xilinx: use u32 for reset ID in reset APIs

Refactors the reset handling mechanisms by replacing the reset ID's
enum type with a u32. This update improves flexibility, allowing the
reset ID to accommodate a broader range of values, including those
that may not fit into predefined enum values.

The use of u32 for reset ID enhances extensibility, especially for
hardware platforms or features where more granular control of reset
operations is required. By shifting to a general integer type, this
change reduces constraints and simplifies integration with other
system components that rely on non-enum-based reset IDs.
