arm: rmobile: r8a7790: Update initialize L2 cache
Initialization of L2CTLR[5] was set only as R8A7790 by commit
237faf095fb43abbed6e40266ef7efccc8b9308b.
However, initialization of cash needs to be performed continuously.
This changes into the processing which continues initialization of
L2CTLR[5] into L2CTLR cash and performs it.
