[U-Boot] [PATCH v2] ppc4xx: Fix EEPROM configuration on Kilauea

[U-Boot] [PATCH v2] ppc4xx: Fix EEPROM configuration on Kilauea

[Stefan Roese]

Kilauea has an AT24C02 EEPROM which has an 8 byte page. Without defining
CONFIG_SYS_EEPROM_PAGE_WRITE_BITS to 3 the "eeprom" command doesn't
work correctly.

Additionally the page write delay (CONFIG_SYS_EEPROM_PAGE_WRITE_DELAY_MS)
is set to a more defensive value of 10ms.

Applied to ppc4xx/master. Thanks.
