panic_handle: make emmc_panic.c work without logger

panic_handle: make emmc_panic.c work without logger

BZ: 32660

When logger is disabled, emmc_ipanic.c is compiled with failure messages because
emmc_ipanic.c depended on logger module. At the same time, logger_pti.c has same issue.

For emmc_iapnic.c, dumping logcat buffer function is enabled only when CONFIG_ANDROID_LOGGER
is set to y. In order to use less macro references, some functions are moved to another
location without any change.
For logger_pti.c, we make ANDROID_LOGGRT_PTI depends on ANDROID_LOGGER. Then logger_pti.c and logger.c
can be enabled/disabled at the same time.
