Implement fix for i.MX 93 silicon errata ERR052021.
ERR052021 uSDHC: Sometimes uSDHC does not work under VDD_SOC low
drive mode and nominal mode
Description:
uSDHC PADs have one integration issue.
When CMD/DATA lines direction change from output to input, uSDHC
controller begin sampling, the integration issue will make input
enable signal from uSDHC propagated to the PAD with a long delay,
thus the new input value on the pad comes to uSDHC lately. The
uSDHC sampled the old input value and the sampling result is wrong.
Workaround:
Set uSDHC CMD/DATA PADs iomux register SION bit to 1, then PADs will
propagate input to uSDHC with no delay, so correct value is sampled.
This issue will wrongly trigger the start bit when sample the USDHC
command response, cause the USDHC trigger command CRC/index/endbit
error, which will finally impact the tuning pass window, especially
will impact the standard tuning logic, and can't find a correct delay
cell to get the best timing.
Based on commit bb89601282 ("arm64: dts: imx93-11x11-evk: set SION for

The phyCORE-i.MX93 SoM comes in two variants, one with VDD_IO set to
3.3V and the other variant to 1.8V. The 3.3V variant can only support
DDR52 mode, while 1.8V variant is capable of HS400ES eMMC mode. The
information about VDD_IO option is encoded in the SoM's EEPROM. EEPROM
is read in the bootloader and bootloader clears the "no-1-8-v" flag in
case of 1.8V SoM variant is detected. Thus add property 'no-1-8-v' by
default to usdhc1 (eMMC) node and let bootloader handle the flag. In
case EEPROM is erased or read-out fails, flag "no-1-8-v" also ensures
fall-back compatibility with both SoM variants.

Some of our devices crash in tb_cfg_request_dequeue():
general protection fault, probably for non-canonical address 0xdead000000000122
CPU: 6 PID: 91007 Comm: kworker/6:2 Tainted: G U W 6.6.65
RIP: 0010:tb_cfg_request_dequeue+0x2d/0xa0
Call Trace:
<TASK>
? tb_cfg_request_dequeue+0x2d/0xa0
tb_cfg_request_work+0x33/0x80
worker_thread+0x386/0x8f0
kthread+0xed/0x110
ret_from_fork+0x38/0x50
ret_from_fork_asm+0x1b/0x30
The circumstances are unclear, however, the theory is that
tb_cfg_request_work() can be scheduled twice for a request:
first time via frame.callback from ring_work() and second
time from tb_cfg_request(). Both times kworkers will execute
tb_cfg_request_dequeue(), which results in double list_del()
from the ctl->request_queue (the list poison deference hints
at it: 0xdead000000000122).
Do not dequeue requests that don't have TB_CFG_REQUEST_ACTIVE
bit set.

Be more informative if memremap fails, and print out physical address
together with size. This change intends to make investigations of such
early failures slightly easier.
