[U-Boot] [PATCH v3 6/6] arm: socfpga: a10: move SPL heap size to Kconfig

[Simon Goldschmidt]

Instead of fixing the SPL heap to 64 KiB in the board config header via
CONFIG_SYS_SPL_MALLOC_SIZE, let's just use CONFIG_SPL_SYS_MALLOC_F_LEN
in the defconfig.

This also has the advantage that it removes sub-mach specific ifdefs in
socfpga_common.h.

Changes in v3:
- fixed summary ("stack" -> "heap")
- enable CONFIG_SPL_CLEAR_BSS_F for socfpga_arria10 using full malloc
  early in SPL
- rebased

Changes in v2: None
