boards: thingy53: Inconsistent method of setting USB related log level

[mkapala-nordic]

Describe the bug
Current method of setting default USB related log levels for Thingy:53 board leads to generating inconsistent configuration:

CONFIG_USB_CDC_ACM_LOG_LEVEL=0
CONFIG_USB_CDC_ACM_LOG_LEVEL_OFF is not set
CONFIG_USB_CDC_ACM_LOG_LEVEL_ERR is not set
CONFIG_USB_CDC_ACM_LOG_LEVEL_WRN is not set
CONFIG_USB_CDC_ACM_LOG_LEVEL_INF=y
CONFIG_USB_CDC_ACM_LOG_LEVEL_DBG is not set

Affected are USB_CDC_ACM_LOG_LEVEL and USB_DEVICE_LOG_LEVEL options.

Expected behavior
Logs config should be consistent:

CONFIG_USB_CDC_ACM_LOG_LEVEL_OFF=y
# CONFIG_USB_CDC_ACM_LOG_LEVEL_ERR is not set
# CONFIG_USB_CDC_ACM_LOG_LEVEL_WRN is not set
# CONFIG_USB_CDC_ACM_LOG_LEVEL_INF is not set
# CONFIG_USB_CDC_ACM_LOG_LEVEL_DBG is not set
CONFIG_USB_CDC_ACM_LOG_LEVEL=0

To Reproduce
Steps to reproduce the behavior:

• Enable CONFIG_LOG=y in prj.conf of hello_world sample
• Build hello_world sample for thingy53_nrf5340_cpuapp
• Check build/zephyr/.config
• Logs related options are inconsistent

Environment (please complete the following information):

• OS: Ubuntu 22.04 LTS
• Toolchain: zephyr sdk 0.15.2
• Commit SHA or Version used: 3.3.0-rc2
