Thara Gopinath 358f0e630d OMAP3: hwmod: support to specify the offset position of various SYSCONFIG register bits. 
In OMAP3 Some modules like Smartreflex do not have the regular sysconfig
register.Instead clockactivity bits are part of another register at a
different bit position than the usual bit positions 8 and 9.

In OMAP4, a new scheme is available  due to the new protocol
between the PRCM and the IPs. Depending of the scheme, the SYSCONFIG
bitfields position will be different.
The IP_REVISION register should be at offset 0x00.
It should contain a SCHEME field. From this we can determine whether
the IP follows legacy scheme or the new scheme.

31:30 SCHEME  Used to distinguish between old scheme and current.
 Read 0x0:  Legacy protocol.
 Read 0x1:  New PRCM protocol defined for new OMAP4 IPs

For legacy IP
 13:12 MIDLEMODE
 11:8  CLOCKACTIVITY
 6     EMUSOFT
 5     EMUFREE
 4:3   SIDLEMODE
 2     ENAWAKEUP
 1     SOFTRESET
 0     AUTOIDLE

For new OMAP4 IP's, the bit position in SYSCONFIG is (for simple target):
 5:4   STANDBYMODE (Ex MIDLEMODE)
 3:2   IDLEMODE (Ex SIDLEMODE)
 1     FREEEMU (Ex EMUFREE)
 0     SOFTRESET

Unfortunately In OMAP4 also some IPs will not follow any of these
two schemes. This is the case at least for McASP, SmartReflex
and some security IPs.

This patch introduces a new field sysc_fields in omap_hwmod_sysconfig which
can be used by the hwmod structures to specify the offsets for the
sysconfig register of the IP.Also two static structures
omap_hwmod_sysc_type1 and omap_hwmod_sysc_type2 are defined
which can be used directly to populate the sysc_fields if the IP follows
legacy or new OMAP4 scheme. If the IP follows none of these two schemes
a new omap_hwmod_sysc_fields structure has to be defined and
passed as part of omap_hwmod_sysconfig.
