ARM i.MX25: Enable all needed clocks during startup 

This enables the following clocks on i.MX25:

PER: esdhc1, esdhc2, i2c, nfc, owire, pwm, uart
AHB: emi, esdhc1, esdhc2, fec, lcdc, usbotg
IPG: cspi1, cspi2, cspi3, esdhc1, esdhc2, fec, gpt1, gpt2, gpt3, gpt4,
iim, LCDC_EN, pwm1, pwm2, pwm3, pwm4, spba, tsc, uart1, uart2, uart3,
uart4, uart5

These are hopefully all the clocks we need for barebox.
