- add missing register defines in struct cm_perpl
epwmss0clkctrl
epwmss2clkctrl
lcdcclkstctrl
- add missing register defines in struct cm_dpll
clklcdcpixelclk
- add struct pwmss_regs
- add struct pwmss_ecap_regs
- add LCD Controller base LCD_CNTL_BASE
- add PWM0 controller base PWMSS0_BASE

- changes for v4:
add comment from Tom Rini:
- rename "reserved" into "resv1" in struct pwmss_ecap_regs
- use <space> not <tab> after "#define"
add this patch to patchserie "arm, am335x: add support for siemens boards"
-> patch marked as v4
