mb/google/fatcat/var/lapis: Remove redundant splash logo alignment

This patch removes logo_valignment from overridetree.cb. The alignment
`FW_SPLASH_VALIGNMENT_CENTER` is the default behavior in the coreboot
splash driver, making this explicit assignment unnecessary.

BUG=none
TEST=Build and boot lapis; verify logo remains centered.
