[PATCH] hw/sd/sdhci: Set reset value of interrupt registers

[BALATON Zoltan <balaton@eik.bme.hu>]

The interrupt enable registers are not reset to 0 but some bits are
enabled on reset. At least some U-Boot versions seem to expect this
and not initialise these registers before expecting interrupts. The
numbers in this patch match what QorIQ P1022 has on reset and fix
U-Boot for this SoC and should not break other drivers that initialise
(and thus overwrite) these reset values.

I've also noticed that the work around marked with an XXX comment near
line 600 breaks the U-Boot I've tested so I need to disable it:
if ((s->sdmasysad % boundary_chk) == 0) {
-        page_aligned = true;
+//        page_aligned = true;
}
What should this hack fix and could it be now removed or somehow
restricted to cases where it's needed?
