The recent change in commit 20cf2aed89ac ("gpio: rockchip: mark the GPIO
controller as sleeping") to mark the rockchip GPIO driver as sleeping
has started triggering the warning at drivers/gpio/gpiolib.c:3523
indicating that a sleepable GPIO was called via the non-sleeping APIs on
the Rock 5B:

<4>[   14.699308] Call trace:
<4>[   14.699545]  gpiod_get_value+0x90/0x98 (P)
<4>[   14.699928]  tx_5v_power_present+0x44/0xd0 [synopsys_hdmirx]
<4>[   14.700446]  hdmirx_delayed_work_hotplug+0x34/0x128 [synopsys_hdmirx]
<4>[   14.701031]  process_one_work+0x14c/0x28c
<4>[   14.701405]  worker_thread+0x184/0x300
<4>[   14.701756]  kthread+0x11c/0x128
<4>[   14.702065]  ret_from_fork+0x10/0x20

Currently the active use of the GPIO is all done from process context so
can be simply converted to use gpiod_get_value_cansleep(). There is one use
of the GPIO from hard interrupt context but this is only done so the status
can be displayed in a debug print so can simply be deleted without any
functional effect.
