uniphier: turn on ENABLE_PIE
Now that various issues in the PIE support have been fixed,
this platform can enable ENABLE_PIE.
I tested BL2_AT_EL3, BL31, TSP, and all of them worked.

BL2_AT_EL3: add PIE support
This implementation simply mimics that of BL31.
I did not implement the ENABLE_PIE support for BL2_IN_XIP_MEM=1 case.
It would make the linker script a bit uglier.

BL31: discard .dynsym .dynstr .hash sections to make ENABLE_PIE work
When I tried ENABLE_PIE for my PLAT=uniphier platform, BL31 crashed
at its entry. When it is built with ENABLE_PIE=1, some sections are
inserted before the executable code.
$ make PLAT=uniphier CROSS_COMPILE=aarch64-linux-gnu- ENABLE_PIE=1 bl31

The previous stage loader generally jumps over to the base address of
BL31, where no valid instruction exists.
I checked the linker script of Linux (arch/arm64/kernel/vmlinux.lds.S)
and U-Boot (arch/arm/cpu/armv8/u-boot.lds), both of which support
relocation. They simply discard those sections.
Do similar in TF-A too.

PIE: pass PIE options only to BL31
docs/getting_started/build-options.rst clearly says ENABLE_PIE is
currently only supported in BL31, but in fact, it has a stronger
limitation:
Defining ENABLE_PIE may corrupt BL1 and BL2. So, ENABLE_PIE is
supported only for platforms where BL31 is the only image built
in the TF-A tree.
Currently, ENABLE_PIE is enabled by two platforms,
plat/arm/common/arm_common.mk and ti/k3/common/plat_common.mk,
both of which enable ENABLE_PIE together with RESET_TO_BL31.
For platforms with the full boot sequence, ENABLE_PIE may break earlier
BL stages. For example, if I build PLAT=qemu with ENABLE_PIE=1, it
fails in BL1.
When ENABLE_PIE is enabled, PIE options are added to TF_CFLAGS and
TF_LDFLAGS, so all BL images are affected. It is problematic because
currently only the BL31 linker script handles it. Even if BL1/BL2
works, the image size would increase needlessly, at least.
Pass the PIE options only to BL images that support it.

Build: support per-BL LDFLAGS
make_helpers/build_macros.mk supports per-BL CFLAGS. For example,
you can pass compiler flags only to BL31 by using BL31_CFLAGS.
This commit adds per-BL LDFLAGS support, which is useful as well.
My main motivation of this addition is to use it for ENABLE_PIE.
When ENABLE_PIE is enabled, some linker flags are added to TF_LDFLAGS,
which affects all the TF images. It will make more sense to pass the
relevant options only to BL images that support it.
