arch: use bit-shift expressions for cache size units

Browse Source 
Replace 1024, 1024u32.pow(2), and 1024u32.pow(3) with 1u32 << 10,
1u32 << 20, and 1u32 << 30 in get_cache_size. The shift form makes
the binary (KiB/MiB/GiB) nature of the conversion immediately
obvious and is easier to read at a glance.
