linux: Add p9 specific defconfig
Add skiroot_p9_defconfig primarily so that we can add kernel command
line options only required for POWER9 systems. In particular
"powersave=off" is required while there are existing issues with cpuidle,
and "quiet" is removed to aid debugging during bringup.
While we're here also trim a few config options that are unlikely to be
required on P9:
CONFIG_BE2ISCSI
CONFIG_SCSI_SYM53C8XX_2
CONFIG_SCSI_SYM53C8XX_DMA_ADDRESSING_MODE
CONFIG_VORTEX
CONFIG_PCNET32
CONFIG_S2IO
CONFIG_MYRI10GE
