ARM: imx25: support silicon revision 1.2
Update the mx25_read_cpu_rev function to recognize silicon revision 1.2
for imx25 chipsets.
Silicon revision 1.2 is mentioned in the errata document at
https://www.nxp.com/docs/en/errata/IMX25CE.pdf. The imx25 chips on my
test boards show revision 1.2 as well.
