[PATCH v2 1/7] sata-imx: i.MX53, use the internal 120MHz clock by default

[Eric Bénard]

this allows SATA to work on i.MX53 QSB-R :
barebox at Freescale i.MX53 Quick Start-R Board:/ ata0.probe=1
imx-sata 10000000.sata: port 0: SATA link ok
imx-sata 10000000.sata: port 0: Spinning up device...
imx-sata 10000000.sata: port 0: ok.
ata0: registered /dev/ata0

before this fix the log was :
barebox at Freescale i.MX53 Quick Start-R Board:/ ata0.probe=1
imx-sata 10000000.sata: port 0: SATA link timeout
set parameter: Connection timed out
