Migrate the generic r8a7740 platform from calling l2x0_of_init() to the
generic l2c OF initialization.

v5:
  - No changes,

v4:
  - This depends on commit eeedcea69e927857 ("ARM: 8395/1: l2c: Add
    support for the "arm,shared-override" property"), which is queued
    for 4.3 in arm/for-next,

v3:
  - Use 0/~0 now DT supports "arm,shared-override",

v2:
  - Keep only {,~}L2C_AUX_CTRL_SHARED_OVERRIDE.
