[PATCH v5 1/5] alpha: move Tsunami machine check handling to err_tsunami.c

[Magnus Lindholm <linmag7@gmail.com>]

Move the existing handler and PCI error clearing helpers without changing
their behavior. Build the error objects for ALPHA_TSUNAMI so that all
Tsunami configurations, including non-generic Shark, can use them.
