thermal: intel: int340x: Fix potential shift overflow in ptc_mmio_write()

Browse source

The value parameter is u32 but is shifted into a u64 register value
without casting first. If the shift amount pushes bits beyond 32, they
are lost. Cast value to u64 before shifting to ensure all bits are
preserved.
