board-xxs1500.c references 2 functions without declaring them, so add
the header file to placate the build.
../arch/mips/alchemy/board-xxs1500.c: In function 'board_setup':
../arch/mips/alchemy/board-xxs1500.c:56:2: error: implicit declaration of function 'alchemy_gpio1_input_enable' [-Werror=implicit-function-declaration]
56 | alchemy_gpio1_input_enable();
../arch/mips/alchemy/board-xxs1500.c:57:2: error: implicit declaration of function 'alchemy_gpio2_enable'; did you mean 'alchemy_uart_enable'? [-Werror=implicit-function-declaration]
57 | alchemy_gpio2_enable();
Fixes: 8e026910fc ("MIPS: Alchemy: merge GPR/MTX-1/XXS1500 board code into single files")
