Hi Srinivas,
Thanks for the patch,
By default NVMEM_SYSFS should be set true, those whose don't want they can
disable the same.
If we go with disable option, there are chances of eeprom
reboots.
This patch adds new NVMEM_SYSFS Kconfig to make binary sysfs entry
an optional one. This provision will give more flexibility to users.
This patch also moves existing sysfs code to a new file so that its
not compiled in when its not really required.
