Depending on the regulator version, the voltage table might be
different. Use version specific regulator tables in order to select
correct voltage table. For the following regulator versions different
voltage tables are now used:
* TPS658623: Use correct voltage table for SM2
* TPS658643: New voltage table for SM2
Both versions are in use on the Colibri T20 module. Make use of the
correct tables by requesting the correct SM2 voltage of 1.8V.
This change is not backward compatible since an old driver is not able
to correctly set that value. The value 1.8V is out of range for the old
driver and will refuse to probe the device. The regulator starts with
default settings and the driver shows appropriate error messages.
On Colibri T20, the old value used to work with TPS658623 since the
driver applied a wrong voltage table too. However, the TPS658643 used
on V1.2 devices uses yet another voltage table and those broke that
pseudo-compatibility. The regulator driver now has the correct voltage
table for both regulator versions and those the correct voltage can be
used in the device tree.

regulator/clk: Fix s2mps11 build
This patch fixes a build failure that appeared in v3.13-rc4 due to an
RTC/MFD update merged via -mm.
Replace calls to sec_reg* helpers with direct usage of regmap API. The
sec_reg* helpers are error-prone as they mix u8 with unsigned int and
order of some of parameters (val and mask in sec_reg_update()).
Also the helpers do not give any way of useful abstraction as they just
call corresponding regmap function.
This patch replaces:
- sec_reg_read() with regmap_read(),
- sec_reg_write() with regmap_write(),
- sec_reg_update() with regmap_update_bits().

A small set of driver fixes plus one larger core change which changes
the way we check to see if we're using DT so that there aren't any races
between deciding we're using DT and the regulator subsystem noticing.
This makes the new support for substituting a dummy regulator and
optional regulators work a lot better on DT systems since it ensures
that we don't trigger probe deferral when we shouldn't which was causing
bugs in clients.

Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and
add new regmap for RTC.
On S5M8767A registers were not properly updated and read due to usage of
the same regmap as the PMIC. This could be observed in various hangs,
e.g. in infinite loop during waiting for UDR field change.
On this chip family the RTC has different I2C address than PMIC so
additional regmap is needed.
