The U_BOOT_DRIVER macro creates a list of drivers used at link time, and
all entries here must be unique. This in turn means that all entries in
the code should also be unique in order to not lead to build failures
later with unexpected build combinations. Typically, the problem we have
here is when a driver is obviously based on another driver and didn't
update this particular field and so while the name field reflects
something unique the linker entry itself is not. In a few places this
provides a more suitable string name as well, however.

Failing to enable clocks will lead to bus hangs and the board crashing
in some cases, let's actually deal with this error and fail probe rather than hoping the clocks are already enabled.

Tom Rini <trini@konsulko.com> says:

As seen by a number of patches fixing memory leaks, U-Boot has a problem
with developer expectations around devm_kmalloc and friends. Namely,
whereas in Linux these memory allocations will be freed automatically in
most cases, in U-Boot this is only true if DEVRES is enabled. Now,
intentionally, in xPL phases, we do not (and do not offer as an option)
enabling DEVRES. However in full U-Boot this is left either to the user,
or some drivers have select'd DEVRES on their own. This inconsistency is
a problem. This series goes and deals with two small issues that were
shown by having all drivers that use devm_.alloc to allocate memory also
select DEVRES and then we make DEVRES no longer be a prompted option and
instead select'd as needed. We do not make this unconditional as it
would result in growing the resulting binary on the many platforms which
have no users of the devm_.alloc family of functions.

The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c8c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).

This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

Exynos7 (and later) HS-I2C blocks have special interrupts regarding
various data transfer states (see HSI2C_INT_I2C_TRANS_EN). Add support
for enabling and handling these interrupt bits.

Add the corresponding compatible, 'samsung,exynos7-hsi2c'. In order to
differentiate between the multiple device variants, an enum is
introduced which is used where difference in implementations exist.
