x86: baytrail: Issue full system reset in reset_cpu()
With MRC cache enabled, when typing 'reset' in the U-Boot shell,
BayTrail FSP initialization hangs at "Configuring Memory Start":
Setting BootMode to 0
Install PPI: 1F4C6F90-B06B-48D8-A201-BAE5F1CD7D56
Register PPI Notify: F894643D-C449-42D1-8EA8-85BDD8C65BDE
About to call MrcInit();
BayleyBay Platform Type
CurrentMrcData.BootMode = 4
Taking Fastboot path!
Configuring Memory Start...
Changing reset_cpu() to do a full system reset fixes this issue.
