OMAP3: igep00x0: add missing include mach-types.h in config.

Current '#if' directives (used in igep00x0.h config file) comparing MACH_TYPE
values in igep00x0.h doesn't work as expected. The comparision between
CONFIG_MACH_TYPE and MACH_TYPE_IGEP0020 is always true independent of the IGEP
machine configured.

For example, following directive

 if (CONFIG_MACH_TYPE == MACH_TYPE_IGEP0020)
    define something
 endif

Is always evaluated true although we configure u-boot for MACH_TYPE_IGEP0030.

The build doesn't shows any error so looks that both defines had always the same
value. Including the mach-types.h file sets properly the value of
MACH_TYPE_IGEPxxxx.

ONENAND, as the technology name is ONENAND this patch replaces
all these defines.

SPL: ONENAND: Fix onenand_spl_load_image implementation.

Tested with an IGEPv2 board seems that current onenand_spl_load_image implementation
doesn't work. This patch fixes this function changing the read loop and reading the
onenand blocks from page to page.

Tested with various IGEP based boards with a OneNAND from Numonyx.
