mtd: m25p80: Use OPCODE_QUAD_READ_4B for 4-byte addressing

commit 3487a639 ("drivers: mtd: m25p80: add
quad read support") in -next added both the 3-byte OPCODE_QUAD_READ and the
4-byte OPCODE_QUAD_READ_4B, but incorrectly uses OPCODE_QUAD_READ for both
3-byte and 4-byte addressing.

Use OPCODE_QUAD_READ_4B in the 4-byte case to fix this.
