accel/ivpu: Split FW runtime and global memory buffers

Split firmware boot parameters (4KB) and FW version (4KB) into dedicated
buffer objects, separating them from the FW runtime memory buffer. This
creates three distinct buffers with independent allocation control.

This enables future modifications, particularly allowing the FW
image memory to be moved into a read-only buffer.

Fix user range starting address from incorrect 0x88000000 (2GB + 128MB)
overlapping global aperture on 37XX to intended 0xa0000000 (2GB + 512MB).
This caused no issues as FW aligned this range to 512MB anyway, but
corrected for consistency.

Convert ivpu_hw_range_init() from inline helper to function with overflow
validation to prevent potential security issues from address range
arithmetic overflows.

Improve readability of ivpu_fw_parse() function, remove unrelated constant
defines and validate firmware header values based on vdev->hw->ranges.
