[PATCH] ARM: dts: stm32: Drop bias-disable from STM32MP15xx DHCOM SoM sdmmc1_b4_pins_a

Drop bias-disable property from STM32MP15xx DHCOM SoM sdmmc1_b4_pins_a
to fix the following DT checker warning. The bias-pull-up property is
the only bias-related property that has to be present in those pinctrl
node subnodes.

"
arch/arm/boot/dts/st/stm32mp153c-dhcom-drc02.dtb: pinctrl@50002000 (st,stm32mp157-pinctrl): sdmmc1-b4-0:pins1: {'pinmux': [10253, 10509, 10765, 11021, 12813], 'slew-rate': 1, 'drive-push-pull': True, 'bias-disable': True, 'bias-pull-up': True} is valid under each of {'required': ['bias-pull-up']}, {'required': ['bias-disable']}
"
