Some of the misc device minor numbers definitions spread in different
local c files, specially some are duplicate number with different
name, some are same name with conflict numbers, some prefer dynamic
minors.
This patchset try to address all of them.
Thanks Willy and Miguel help building test on ARM arch, no new change
on ARM part in v2 so it should pass build on ARM obviously.
PATCH3 "speakup: misc: Use dynamic minor numbers for speakup devices"
is dropped in v2, will process it separately if there is response from
maintainer later.
v2:
PATCH1: keep HWRNG_MINOR name and fix RNG_MISCDEV_MINOR per Herbert.
PATCH2: fix typo error with PXA3XX_GCU_MINOR per Arnd.
Zhenzhong Duan (2):
misc: cleanup minor number definitions in c file into miscdevice.h
misc: move FLASH_MINOR into miscdevice.h and fix conflicts

1.8.3.1
FLASH_MINOR is used in both drivers/char/nwflash.c and
drivers/sbus/char/flash.c with conflict minor numbers.
Move all the definitions of FLASH_MINOR into miscdevice.h.
Rename FLASH_MINOR for drivers/char/nwflash.c to NWFLASH_MINOR
and FLASH_MINOR for drivers/sbus/char/flash.c to SBUS_FLASH_MINOR.

HWRNG_MINOR and RNG_MISCDEV_MINOR are duplicate definitions, use
unified HWRNG_MINOR instead and moved into miscdevice.h
ANSLCD_MINOR and LCD_MINOR are duplicate definitions, use unified

MISCDEV_MINOR is renamed to PXA3XX_GCU_MINOR and moved into

Other definitions are just moved without any change.
