[PULL 26/30] target/ppc: Remove msr_ts macro

[Daniel Henrique Barboza <danielhb413@gmail.com>]

From: Víctor Colombo <victor.colombo@eldorado.org.br>

msr_ts macro hides the usage of env->msr, which is a bad
behavior. Substitute it with FIELD_EX64 calls that explicitly use
env->msr as a parameter.
