ppc4xx: Make output a little shorter on I2C bootrom detection

Most 4xx PPC capable of using an I2C bootrom for bootstrap setting
already print a line with the information which I2C bootrom is
used for bootstrap configuration. So we don't need this extra line
with "I2C boot EEPROM en-/dis-abled".

This patch also has a little code cleanup integrated.
