p9_sbe_tp_switch_gears -- skip i2c access outside of SBE platform
additional updates after review with Srinivas/Soma
remove clearing of PERV_CTRL0_SET_TP_PLLBYP_DC (covered in p9_sbe_npll_setup)
guard all i2c setup code to apply to SBE only
will execute in Cronus platform (forthcoming p9_sbe_clock_test2 code)
