The NVIDIA's Tegra KBC has maximum 24 pins to make matrix keypad.
Any pin can be configured as row or column. The maximum column pin
can be 8 and maximum row pin can be 16.
Remove the assumption that all first 16 pins will be used as row
and remaining as columns and Add the property for configurin
Tegra KBC driver have the default key mapping for 16x8 configuration.
The key mapping can be provided through platform data or through DT
and the mapping varies from platform to platform, hence this default
mapping is not so useful. Remove the default mapping to reduce the code
lines of the driver.
This patch series:
- fix build warning,
- use devm_* for allocation,
- make column/rows configuration through DT and
- remove the rarely used key mapping table.
Changes from V1:
- renames the rows and pins property array.
- nit cleanups.

This patch sets ldo->en_pin to NULL if lp8788_gpio_request_ldo_en() fails, then
we can use it to determinate if the regulator is controlled by external pin or

Inside bus_add_driver(), one device might be added(device_add()) into
the bus or probed which is triggered by deferred probe
just after completing of driver_attach() and before
'klist_add_tail(&priv->knode_bus, &bus->p->klist_drivers)',
so the device won't be probed by this driver.
