Replace manual character checks (e.g., buf[0] == '1') with the standard
kstrtobool() API in sysfs store functions.

Signed-off-by: Abdelnasser Hussein <abdelnasserhussein11@gmail.com>
---
Changes in v4:
- Removed Joshua's Reviewed-by tag.

Changes in v3:
- Change _adt7316_store_enabled() parameter type from int to bool to match callers (Andy Shevchenko).
- Update adt7316_disable() and adt7316_enable() to pass false/true instead of 0/1 (Andy Shevchenko).

Changes in v2:
- Include <linux/kstrtox.h>.
- Rename the boolean variable from 'req' to 'val' for clarity.
- Add Reviewed-by tag from Joshua Crofts.

Ah. No need to resend just to drop a tag.  I did that on v3.

Anyhow, all is well that ends well!

Thanks,
