ARM: 7162/1: errata: tidy up Kconfig options for PL310 errata workarounds
The Kconfig options for the PL310 errata workarounds do not use a consistent naming scheme for either the config option or the bool description. This patch tidies up the options by ensuring that the bool descriptions are prefixed with "PL310 errata:" and the config options are prefixed with PL310_ERRATA_, making it much clearer in menuconfig as to what the workarounds are for.
