[U-Boot] [PATCH v2 0/4] driver: ti_qspi: Use a SYSCON device to map the ctrl_mod_mmap register

[Jean-Jacques Hiblot]

This series allows the ti_qspi driver to use the same dts description as the
linux kernel. In Linux since 4.6 the ctrl_mod_mmap is described in the DTS as a
syscon. It used to be the 3rd memory range in "reg".

The first two patches of this series are generic ones:
 * Allow the SPL version of fdtdec_get_addr_size_fixed() to perform address
   translation
 * change the regmap initialization to take in account the required address
   translation by using fdtdec_get_addr_size_fixed().

The third patch adds the mechanism in the ti_qspi driver to get the address
of ctrl_mod_mmap from the syscon

The last patch simply enable the SYSCON feature in the default config for the
dra7xx and am57xx evms.

changes since v1:
 * rebased on top of Lokesh's series enabling support for SPL_DM][1][2]
 * Added a patch to enable address translation in fdtdec_get_addr_size_fixed()
 * use CONFIG_IS_ENABLED(XXX) instead of CONFIG_XXX and CONFIG_SPL_XXX to
   simplify the conditional code.
