Hence it is replaced with i2c_set_bus_num() function call.

ff2d57ea5e palmas: use palmas_i2c_[read|write]_u8
commit 21144298 (power: twl6035: add palmas PMIC support)
introduced twl6035_i2c_[read|write]_u8
Then, commit dd23e59d (omap5: pbias ldo9 turn on)
introduced palmas_[read|write]_u8 for precisely the same access
function. TWL6035 belongs to the palmas family, so instead of having
an twl6035 API, we could use an generic palmas API instead.

To stay consistent with the function naming of twl4030,6030 accessors,
we use palmas_i2c_[read|write]_u8

61712bcad4 twl4030: fix potential power supply handling issues
twl4030_pmrecv_vsel_cfg currently first sets up device group (effectively
enabling the supply), and only then sets vsel (selects voltage). This could
lead to wrong voltage for a short time, or even long time if second i2c
write fails.

Fix this by writing vsel first and device group after that. Also
introduce error checking to not enable the supply if we failed to set
the voltage, and start logging errors as power supply problems are
usually important.

6d8962e814 Switch from archive libraries to partial linking
Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.
