samples: fix bootloaders warnings

Remove mcuboot board overlays for _ns variant,
mcuboot always use secure images.
Fix warning was assigned 'y' but got 'n':
* FPROTECT_ALLOW_COMBINED_REGIONS on nrf54l15
* MBEDTLS_CFG_FILE on nrf52840
Remove redundant PM_MCUBOOT_PAD configuration.
Remove log configuration from board overlays.
