mtd: rawnand: lpc32xx_mlc: fix irq handler prototype

clang-16 warns about mismatched function prototypes:

drivers/mtd/nand/raw/lpc32xx_mlc.c:783:29: error: cast from 'irqreturn_t (*)(int, struct lpc32xx_nand_host *)' (aka 'enum irqreturn (*)(int, struct lpc32xx_nand_host *)') to 'irq_handler_t' (aka 'enum irqreturn (*)(int, void *)') converts to incompatible function type [-Werror,-Wcast-function-type-strict]

Change the interrupt handler to the normal way of just passing
a void* pointer and converting it inside the function..

Fixes: 70f7cb78ec53 ("mtd: add LPC32xx MLC NAND driver")
