intel_adsp: adsp_memory: update cAVS 2.5 memory definitions

Browse source 
This commit updates the device tree and memory header file
for the Intel cAVS 2.5 platform to define the LSBPM and
HSBPM registers.

Changes include:
- Added node definitions for 'lsbpm' and 'hsbpm' in
intel_adsp_cavs25.dtsi and intel_adsp_cavs25_tgph.dtsi
- Updated adsp_memory.h
