Subject: [PATCH v2 4/4] ARM: exynos: clear prefetch bits in default l2c_aux_val

Clear the L310_AUX_CTRL_DATA_PREFETCH and L310_AUX_CTRL_INSTR_PREFETCH
bits in the l2c_aux_val defaults for Exynos since they can now be set
using the standard l2c2x0 devicetree bindings.

Signed-off-by: Guillaume Tucker <guillaume.tucker@...labora.com>

Notes:
    v2: split patch to only clear exynos platform register bits
