test/py GPIO failure in u-boot/master

[Stephen Warren]

Latest u-boot/master is failing a couple test/py test_ut tests for GPIO:

This was introduced by one of the following changes; I'd assume due to
the GPIO patch:

> cmd: part: Add subcommand to list supported partition tables (detail)
> cmd: fs: Add command to list supported fs types (detail)
> cmd: dm: Fixed/Added DM driver listing subcommands (detail)
> cmd: blkls: Add blkls command (detail)
> image: Add support for ZSTD decompression (detail)
> Actions: OWL: Calculate SDRAM size (detail)
> arm: actions: remove "CONFIG_SYS_SDRAM_SIZE" for Actions Owl Semi SoCs (detail)
> clk: actions: Add Ethernet clocks (detail)
> net: phy: realtek: Add support for RTL8201F PHY module. (detail)
> net: phy: realtek: Introduce PHY_RTL8201F_S700_RMII_TIMINGS to adjust (detail)
> net: designware: s700: Add glue code for S700 mac (detail)
> arm: dts: s700: add node for ethernet controller (detail)
> owl: Kconfig: Enable DM eth for OWL platform (detail)
> configs: Enable mac and phy configs (detail)
> gpio: search for gpio label if gpio is not found through bank name (detail)
> test_sleep.py: make sleep time and margin configurable (detail)
> fs: fat_write: fix short name creation. (detail)

I see what was probably an attempt to fix this:

> commit 7012865e961ca2645d783adf4b75ca4abdbfe5a7 (u-boot/master)
> Author: Heiko Schocher <hs at denx.de>
> Date:   Wed Jul 8 10:24:00 2020 +0200
> 
>     gpio: fix test.py for gpio label lookup

... but the tests are still failing after that. Did that patch edit the
wrong defconfig, or is there an incremental build issue that prevented
that patch being effective?
