gpio: serial: max310x: Use HW type for gpio_chip's label
Some debugging tools (/sys/kernel/debug/gpio, `lsgpio`) use the
gpio_chip's label for displaying an additional context. Right now, the
information duplicates stuff which is already available from the
parent's device. This is how e.g. `lsgpio`'s output looks like:
GPIO chip: gpiochip2, "spi1.2", 16 GPIO lines
Comparing the output of other GPIO expanders that I have available:
gpiochip4: GPIOs 464-479, parent: spi/spi1.1, mcp23s17, can sleep:
gpiochip5: GPIOs 448-463, parent: i2c/0-0020, pca9555, can sleep:
gpiochip2: GPIOs 496-511, parent: spi/spi1.2, spi1.2, can sleep:
This patch ensures that the type of the real HW device is shown instead
of duplicating the SPI path:
gpiochip2: GPIOs 496-511, parent: spi/spi1.2, MAX14830, can sleep:
