[PATCH] at91_ide: remove custom tf_{read|load}() methods (take 2)

[PATCH] at91_ide: remove custom tf_{read|load}() methods (take 2)

[Sergei Shtylyov]

Since tf_{read|load}() methods of this driver have now become identical to their
standard counterparts using MMIO accesses, there's no need to override those
anymore...
