soc/amd/sabrina: Re-init eSPI in bootblock
Currently bootblock does not initialize eSPI if it is already done in
PSP verstage. But some other component is clobbering the eSPI
configuration causing timeouts in EC communication after the boot flow
hits x86. To workaround this issue, re-initialize eSPI in bootblock.
BUG=b:217414563
TEST=Build and boot to OS in Skyrim with PSP verstage.
