Second set of u-boot-atmel fixes for 2021.01 cycle

This set includes very important fixes for: MMC booting on several
boards, drive strength on sam9x60ek mmc lines, compile issues for
timer.c old driver, removal of unwanted access to sam9x60 bit for
oscillator bypass mode, and eeproms read on sama5d2_icp.
