Subject: [PATCH] leds: rgb: mt6370: Fix implicit declaration for FIELD_GET

From: ChiYuan Huang <cy_huang@...htek.com>

0-DAY CI Kernel Test Service reported the implicit declaration error below:

drivers/leds/rgb/leds-mt6370-rgb.c: In function'mt6370_check_vendor_info':
>> drivers/leds/rgb/leds-mt6370-rgb.c:889:15: error: implicit  declaration
   of function 'FIELD_GET' [-Werror=implicit-function-declaration]
  889 |         vid = FIELD_GET(MT6370_VENDOR_ID_MASK, devinfo);
      |

Add the missing header 'bitfield.h' to fix it.
