[PATCH] bus: ti-sysc: Fix missing AM35xx SoC matching

[Adam Ford]

Commit feaa8baee82a ("bus: ti-sysc: Implement SoC revision handling")
created a list of SoC types searching for strings based on names
and wildcards which associates the SoC to different families.

The OMAP34xx and OMAP35xx are treated as SOC_3430 while
OMAP36xx and OMAP37xx are treated as SOC_3630, but the AM35xx
isn't listed.

The AM35xx is mostly an OMAP3430, and a later commit a12315d6d270
("bus: ti-sysc: Make omap3 gpt12 quirk handling SoC specific") looks
for the SOC type and behaves in a certain way if it's SOC_3430.

This caused a regression on the AM3517 causing it to return two
errors:

 ti-sysc: probe of 48318000.target-module failed with error -16
 ti-sysc: probe of 49032000.target-module failed with error -16

Fix this by treating the AM35xx as a SOC_3430, and the error
conditions will disappear.

Looks good to me except let's just add SOC_AM35 to enum sysc_soc rather
than tag am3517 with SOC_3430. We already have checks for SOC_3430 for
several devices and the quirks may not be compatible across AM35 and 3430.
