stoneyridge: Increase SMM stack size to 2K
GSMI Set Event Log is taking more than 1K in stack. This causes the stack to overflow into the adjacent stack. This has the side effect of causing any CPU waiting for the SMI handler to complete to crash when the lock is unlocked because the return pointer has been smashed. BUG=b:80539294 TEST=built on grunt and tested by running `halt` from the OS.
