Subject: [PATCH] ARM: debug: Remove unsupported operand from Kconfig.debug

arm builds show the following warning.

arch/arm/Kconfig.debug:1576:warning: ignoring unsupported character '>'

This is due to

config DEBUG_UART_8250_WORD
	bool "Use 32-bit accesses for 8250 UART"
	depends on DEBUG_LL_UART_8250 || DEBUG_UART_8250
	depends on DEBUG_UART_8250_SHIFT >= 2

This may create the false expectation that DEBUG_UART_8250_WORD
is enabled if DEBUG_UART_8250_SHIFT is larger than 2, so drop the '>'.

Fixes: 0b4cccbec606 ("ARM: debug: add support for word accesses to
	debug/8250.S")
