xtensa: add missing isync to the cpu_reset TLB code

commit cd8869f4cb257f22b89495ca40f5281e58ba359c upstream.

ITLB entry modifications must be followed by the isync instruction
before the new entries are possibly used. cpu_reset lacks one isync
between ITLB way 6 initialization and jump to the identity mapping.
Add missing isync to xtensa cpu_reset.
