Changes for omap1 variants for v4.21 merge window

Browse Source 
In this set of changes Aaro Koskinen revives Palm Tungsten E for the
 MMC and USB making it usable again. And Janusz Krzysztofik follows up
 on the clean-up of  ams-delta GPIO handling. The other changes are
 clean-up for DEFINE_SHOW_ATTRIBUTE by Yangtao Li.

Changes for omap1 variants for v4.21 merge window

In this set of changes Aaro Koskinen revives Palm Tungsten E for the
MMC and USB making it usable again. And Janusz Krzysztofik follows up
on the clean-up of  ams-delta GPIO handling. The other changes are
clean-up for DEFINE_SHOW_ATTRIBUTE by Yangtao Li.

* tag 'omap-for-v4.21/omap1-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
  ARM: OMAP1: fix USB configuration for device-only setups
  ARM: OMAP1: add MMC configuration for Palm Tungsten E
  ARM: OMAP1: devices: configure omap1_spi100k only on OMAP7xx
  ARM: OMAP1/2: fix SoC name printing
  ARM: OMAP1: ams-delta: Move AMS_DELTA_LATCH2_NGPIO to the board file
  ARM: OMAP1: ams-delta: Drop unused symbols from the board header
  ARM: OMAP1: ams-delta: Drop board specific global GPIO numbers
  ARM: OMAP: PM: Change to use DEFINE_SHOW_ATTRIBUTE macro
  ARM: OMAP1: clock: Change to use DEFINE_SHOW_ATTRIBUTE macro
  ARM: OMAP1: ams-delta: Provide GPIO lookup table for LED device
  ARM: OMAP1: ams-delta: make board header file local to mach-omap1
