We already mitigate erratum 1188873 affecting Cortex-A76 and Neoverse-N1 r0p0 to r2p0. It turns out that revisions r0p0 to r3p1 of the same cores are affected by erratum1418040, which has the same workaround as 1188873. Let's expand the range of affected revisions to match1418040, and repaint all occurences of 1188873 to1418040. Whilst we're there, do a bit of reformating in silicon-errata.txt and drop a now unnecessary dependency on ARM_ARCH_TIMER_OOL_WORKAROUND.
