CONFIG_CONSOLE_SYSLOG and CONFIG_SYSLOG_CONSOLE are misleading

[raiden00pl]

These options are misleading.

All other console enable options have the format like CONFIG_{device_name}_CONSOLE, but for SYSLOG it is CONFIG_CONSOLE_SYSLOG. Moreover there is CONFIG_SYSLOG_CONSOLE option but it has different purpose than other options with format CONFIG_{device_name}_CONSOLE.

config SYSLOG_CONSOLE
	bool "Log to /dev/console"
	default !ARCH_LOWPUTC && !SYSLOG_CHAR && !RAMLOG_SYSLOG && !SYSLOG_RPMSG && !SYSLOG_RTT
	depends on DEV_CONSOLE
	---help---
		Use the system console as a SYSLOG output device.

config CONSOLE_SYSLOG
	bool "Use SYSLOG for /dev/console"
	default n
	depends on DEV_CONSOLE && !SYSLOG_CONSOLE
	---help---
		Use the syslog logging device as a system console. If this feature is
		enabled (along with DEV_CONSOLE), then all console output will be
		re-directed to syslog output (syslog_putc). This is useful, for
		example, if the only console is a Telnet console.  Then in that case,
		console output from non-Telnet threads will go to the syslog output.

I think CONFIG_CONSOLE_SYSLOG actually should be called CONFIG_SYSLOG_CONSOLE and actual CONFIG_SYSLOG_CONSOLE should be rename to CONFIG_SYSLOG_CONSOLE_FOR_LOG.

I think it is a good ideal to keep the consistence "CONFIG_{device_name}_CONSOLE" because we could create a CI check to detect two or more "*_CONSOLE " in defconfig and avoid include it into mainline.

I agree that consistency is important, but on the other hand this change will break many user configs, so it will be important to document it well
