load_payload: Use 32-bit accesses to speed up decompression.

Flash prefers 32-bit sequential access. On some platforms ROM is
    not cached due to i.a. MTRR shortage. Moreover ROM caching is not
    currently enabled by default. With this patch payload decompression
    is sped up by theoretical factor of 4.

Test on X201, with caching disabled:

Before:
      90:load payload                  4,470,841 (24,505)
      99:selfboot jump                 6,073,812 (1,602,971)

After:
      90:load payload                  4,530,979 (17,728)
      99:selfboot jump                 5,103,408 (572,429)
