ARM: l2c: ux500: remove cache size override
The cache size should already be present in the L2 cache auxiliary
control register: it is part of the integration process to configure
the hardware IP. Most platforms get this right, yet still many
cargo-cult program, and assume that they always need specifying to
the L2 cache code. Remove them so we can find out which really need
this.
