The commit e8e9715df2 ("regulator: fixed: Modify enable-active-high behavior")
fixed the regulator driver behavior when 'enable-active-high' is defined.
Unfortunately, this patch used dm_regulator_platdata()'s "boot_on" member
to set GPIOD_IS_OUT_ACTIVE flag and enable the regulator.
The issue here is that regulator_common_ofdata_to_platdata() is called
_before_ regulator_pre_probe() function in which the 'regulator-boot-on'
property is asserted.
As a result the GPIOD_IS_OUT_ACTIVE flag is not set and gpio_request_by_name()
called in the former function is not enabling the regulator.
This is problematic for e.g. i.MX ethernet driver, which then tries to
perform initialization without power (and fails).
The solution here is to explicitly enable regulator in regulator_pre_probe()
callback only when 'regulator-boot-on' property is present in device tree.
The GPIOD_IS_OUT_ACTIVE flag is not set at all, but relevant gpio is
requested.

Due to the two-instruction sequence needed to access arbitrary memory
locations, the RISC-V linker aggressively optimises memory accesses and
jumps at link-time. This is called "linker relaxation," and is discussed
in this SiFive article
<https://www.sifive.com/blog/all-aboard-part-3-linker-relaxation-in-riscv-toolchain>.
One of the optimizations in place is to assume that the __global_pointer
symbol is placed in the gp register. To quote the article:
"...The magic __global_pointer$ symbol is defined to point 0x800 bytes
past the start of the .sdata section. The 0x800 magic number allows
signed 12-bit offsets from __global_pointer$ to address symbols at the
start of the .sdata section. The linker assumes that if this symbol is
defined, then the gp register contains that value, which it can then use
to relax accesses to global symbols within that 12-bit range. The
compiler treats the gp register as a constant so it doesn't need to be
saved or restored, which means it is generally only written by _start,
the ELF entry point."
However, U-Boot instead keeps the global data pointer in gp. This causes
memory accesses and jumps optimized to use the gp pointer to fail. To
fix this problem, we undefine the __global_pointer symbol.

The 'enable-active-high' DTS property configures GPIO so it is active with
HIGH state (by default it is low).
The 'regulator-boot-on' property indicates that the regulator was enabled
in the 'earlier' stage - i.e. bootloader/firmware.
In the XEA case the 'fec-3v3' was configured (as a "wrapper" on GPIO0_0) in
