Vladimir Serbinenko 3d6ffe76f8 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)
