[PATCH 1/5] hwrng: bcm2835 - Constify bcm2835_rng_devtype[]

[Rikard Falkeborn]

bcm2835_rng_devtype[] is not modified and can be made const to allow the
compiler to put it in read-only memory.

Before:
   text    data     bss     dec     hex filename
   2392     176       0    2568     a08 drivers/char/hw_random/bcm2835-rng.o

After:
   text    data     bss     dec     hex filename
   2464     104       0    2568     a08 drivers/char/hw_random/bcm2835-rng.o
