boot/uboot: fix missing host-openssl for i.MX28 target

Browse Source 
Building an U-Boot image for the i.MX23 or i.MX28 target requires to run the
bootloaders 'mxsimage' tool on the host. As mxsimage needs unconditionally
OpenSSL, building U-Boot for those targets fails if it is not available on
the host:

tools/mxsimage.c:18:25: fatal error: openssl/evp.h: No such file or directory
  #include <openssl/evp.h>

Add the required dependency 'host-openssl' to all the different U-Boot image
types used to build a bootloader image for an i.MX23/i.MX28 target.

Also pass HOST_CFLAGS and HOST_LDFLAGS to the U-Boot build process so the right
-I/-L options will be used to find OpenSSL.
