1. Convert all linker symbols to char[] type so that we can get the
corresponding address by calling array name 'var' or its address
'&var'. In this way, we can avoid some potential issues[1].
2. Remove unused symbol '_TEXT_BASE'. It has been abandoned and has
not been referenced by any source code.
3. Move '__data_end' to the arch x86's own sections header as it's
only used by x86 arch.
4. Remove some duplicate declared linker symbols. Now we use the
standard header file to declare them.
[1] This patch fixes the boot failure on MIPS target. Error log:

pinctrl_wdog already marked u-boot,dm-spl, so clean up board code.
The set_wdog_reset() function is not necessary as this is handled by
the imx_watchdog.c driver due to the 'fsl,ext-reset-output' property
being set.

Enable DM_SERIAL for both U_Boot and the SPL. The uart4 and its pinmux
are already marked with u-boot,dm-spl but we need to move the call to
preloader_console_init() after spl_init() to avoid a board hang
as dm can't be used until after spl_init().
Remove the manual config of the UART pinmux now that it is no longer
needed.
