platform/x86/intel/tpmi: Use 32 bit aligned address for debugfs mem write

Browse source

The memory write feature supports 32-bit writes to any TPMI offset.
However, future hardware generations may not allow writes to non-32-bit
aligned addresses due to hardware optimizations.

Since all TPMI addresses are 64-bit aligned and correspond to 64-bit
registers, enforce 32-bit alignment for write operations.
